Pays 25k a year for tuition...ends up being taught by a youtube tutor (both chemistry and calculus)...what a great system lol
Thanks for making great videos so I can learn this stuff!
wow that is one expensive school.
oh boy my parents pay 40k a year for tuition. i always end up at youtube for tutors that i can easily understand
@@nanamikents1760 go to france
College is way too expensive, often not worth the money unless your major can make 6 figs
dude im learning this in AP chem lol
What calculator are you using?
deadass saved my life on this one 3am grind with these vids
three years later, im doing the exact same thing at the same time in the morning lmao

This channel is going to be the only reason I pass chemistry
same over here
@@1829Emily hi
at least you're gonna pass..
unlike me
@@red-sv2qf You are going to pass I know you will. I used to get F's but after discovering this channel I get C's and B's, if I'm lucky and A.
im using this for physics.
i'm dying to know who this person is. such an angel
Bro saved my life
Same, i literally have an entirely new career bc he empowered me to learn chemistry
i get the base number right, but not the exponents :'(
press ENG after you get the base number
2 years hhhhhhhhh\
@@muhali5136 how do i write 500 nanometer to 500 x 10 something? i wanna know
1:37 how did u get -22 from -34 and 9
You saved me from miserably failing my test over electron configuration
Fannı. I’m about to fail mine 😂
2 years ago original comment, 1year ago reply above, and now I take mine today
I take mine the 23rd
I’m literally abt to take my test n I’m gonna fail
@@tapesnsnippets i take mine in 2 weeks over electron configuration lmaooo
is anyone else not getting the same answers as he is? I'm typing in everything correctly and my numbers are very different than his. I've also tried two different calculators
If you’re talking about 3:47, I got it wrong as well. Turns out, you have to divide by 5.00 x 10^-9, not 500. Thats what worked for me.
@@alyssarose2818 You're a life saver! I was wondering where -19 came from when I recalculated again and still got 3.98*10^-37
Ah nope my exponents are still not matching up :(
@@spcchckn ~ make sure to use parentheses if you’re using a calculator!
@@spcchcknparenthesis for each thing
Where did you get the exponent -19????
Mass of electron is 1.6*10^-19 it is fixed
I learned so much in so little time!! Thank you Professor!
How do you put this in the calculator, I always get the wrong exponent.
Did you ever figure it out?
I'm getting 3.98x10^-17. I have everything bracketed, what am i doing wrong?
ThePixelFighter calculator might be set to radiant not degrees , change that in the mode setting
Bro I’m so confused
How?
help I got 3.9756E-37 how do I convert it to 3.98E-19
i really appreciate your voice, tone, pace and the way you explain things. it's relaxing yet still engaging to listen to.
You're life saver, it seems very easy to me now❤️
Thanks alot👍
This helped me so much, thank you.
This channel is such a life saver
For Problem #2 and #3, if anyone got the exponent - 31 using a scientific calculator, and it didn't align with the video which is - 19, simply add brackets to those 3 given, and add a multiplication sign between the two converging parentheses.
For example
(6.626 x 10^-34) x (3 x 10^8) ÷ (240 x 10^-9)
Which would equate to
8.28 x 10^-19
As per shown in the video.
If you get
8.28 x 10^-31
Instead, its because you forgot the parentheses, and that multiplication sign in between i guess.
This was very helpful, thanks so much
Professor Organic Chemistry Tutor, thank you for another great video/lecture on How To Calculate The Energy of a Photon Given the Frequency and Wavelength in General/AP Chemistry. This material is easy to follow provided that the correct formula is used to produce the solution. This is an error free video/lecture on UA-cam TV with the Organic Chemistry Tutor.
I got the answer but why it's raised to the power of -19 instead of -37?
same im trying to understand this too. glad im not the only one
Calculate the energy for a single photon of two lights given below (h = 6.626 x 10-34 J s). Do the energy values make sense? How? (𝑬 = 𝒉𝝂 = 𝒉𝒄), (𝑐 = 3.00×108 𝑚/𝑠),
(h = 6.626 x 10-34 J s) (109 nm= 1m)
DUUUUUUUUUUUUUUUUUUUUUUDE I GET IT NOW !! IN THE UNIVERST I'LL BE LIKE "WTF IS THIS" XD
How do you get the -19 part tho because when I do it I get 17
How re you this good in explaining stuff
New Photon equation
P=ETC2 vs E=mc2
Please share
Thank you so much! So simple and straight forward😊👍
For problem #2 Make sure you put brackets around them like this: (6.626x10^-34)x(3x10^8)/(500x10^-9)
Thanks, Obama
Oh my God. I can't explain how i am so thankful of you sharing this. I am assigned as a student teacher tommorow for Science and afraid i might teach my classmates the wrong way! Thats why i am also confused as to why the answer in my calculator is different from the video, so its all about adding brackets.
The thing is, _when will you add brackets?_
PUTANGINA!❤ IN LOVE NA YATA AKO SA CREATOR NG CHANNEL NA ITO. YOU ALWAYS SAVE MY ASS SA MGA MAJOR SUBJECTS KO *SIGHS*. PUTA, GUSTO NA ATA KITA PAKASALAN. ❤❤❤

im not getting the same exponents
Womp womp
I hate chemistry wtf does this shit mean
Thanks,now I may have a chance at my Physics exam
Best video ever ! Literally saving me right now !
HELP! My exponent is not -19. What am I doing wrong???
Same dude I got -18, I think we are right
Hello Friend. Please upload videos on UV/VIS, IR, 1H-NMR, 13C NMR and Mass Spectrometry. These important topics are underrated on UA-cam.
Thank you so much! I was so confused but this was amazing and now I understand!!!
help. For number 2, I typed the equation and I used a energy calculator, but I got 2.4797 eV both times. Help
how did he get the -22?
How to calculate without using calculators?
7:48 I typed in everything exactly like it was on screen and I got 1.325 E to the -33. I use the EE for all the 10 to the (insert power) on my TI 84 + calculator. It is set to degrees. Why am I not getting 1.325 E to the -18 as shown on screen?
you're probably not including the parenthesis for the first number as well
@@kairymizu9530 What does this mean 😭
@@kairymizu9530 I'm having the same problem
how come im not getting the same number of sig figs as him? the number is correct, but i have more sig figs for some reason
These videos are the only ones I am completely okay watching ads for. You deserve it
Did he get 6:31 wrong? It's supposed to be 8.28x10^-17, not -19, right??
I got 8.28X10^-19 as well
For the second problem, how do I put all that in a calculator? I keep getting syntax errors
help I got 3.9756E-37 how do I convert it to 3.98E-19
Me too, i keep getting this number lol. Can't get ^19
@@Kabcde-02 I got -18 lol I checked everything I did
Why does my calculator give me 3.98x10^-37 ??
I'm using a TI-36X Pro. I get the same answer as you. But i use my iPhone, i get the right answer.
Make sure you to put brackets around them like this: (6.26x10^-34)x(3x10^8)/(500x10^-9)
New Veganing because your calculator might be on radiant not degrees, to change it to degrees go to mode then scroll down to degree and click on it
my calc is on degree and i am getting the -37 as well
you did the unit conversion wrong it should be 240(10^-9/1) not 240(1/10^-9)
My calculator ain't giving me the right exponents but answer. However u made me pass my first semester of chemistryif I never came to u I probably would have failed
Wow your better than my teacher
Photons don't have a frequency. Photons are quanta of energy. Their only properties are energy, momentum and angular momentum. Please stop putting nonsensical ideas in student's minds by asking them to solve nonsensical problems.
It is nonsense to calculate energy of photons with the plank constant which obviously has to do with mass , and expressed in its SI unit as J*Hz =J*s = kg(m^2/s^2)s = kg m^2 /s , while mass of a photon = zero
You guys are a a representation of copying nonsense
I'm a software engineer with zero chemistry i was working on a light simulation using rendering this is helpful thanks
Thank you so much...... your explanation helped me a lot
My boy. I think you made an error. Saw it in my book and in google. 3:00. It would be 500X10^-7 m.
Let that be a lesson to all of you guys.
How did you get ×10^-22 ?? i understood everything else jus not how you got that. Btw i jus started learning this subject 😅
Mid-year Physics exam tomorrow and i was completely unaware of this entire topic because I was admitted to the grippy sock hotel when the teacher did this
Ok so I’m confused on how you get the product with the sci. Notation, can anyone help explain
Thanks american I am from India
😂
Thanks for such a video
Love from 🇮🇳 india
can u be my tutor for chemistry

Thanks so much! This video helped me a lot with Inorganic Chem.🙏
This's the only channel that makes me love Chemistry.
Wait....why the exponent of 10 is -22 here 1:36
Dude, ur video helps me a lot!!!! Thank you soooooooooo much!! )
Oh yea it’s all coming together now
Thank you 😩♥️ your my lifesaver
Life saver you are! Fine master you will become
i hate whoever told me chemistry was easy.
I have a test in like 20 mins tysm
Is this Walter junior
I wonder if this guy ever gets tired of the comments saying how broken the school system is or how he saved them from chemistry. Well, THANKS ANYWAY
I don't know if anyone will see this, but I have a question where it has given me wavelength (302 nm) and it wants me to find mass of a photon. I'm very lost if anyone knows how to solve it let me know.
I love your videos but please 🙏I can barely hear you you aren't audible enough most times I can't make out what you're saying
But how you calculate H???
How Planck did it?
Nobody knows.
I've been searching for days in UA-cam, and nobody knows how to find H the way Planck did it.
What kind calculater use to calculate this
How did you get the exponent -19?😭😭
Thank fucking god the way the chem teacher explained this amdde it seem like giga brained massive math but in reality its just plug in stuff in equation thank god for this video
why does my calculator give the wrong exponents after I do these calculations?
at 1:47 , the 1.82 x 10^-22 J is applied through 275x10^9 cycles or 275x10^9 wavelengths not by just one photon . One photon would be one wavelength or one cycle which is 6.626x10^-34 J which is the energy of ANY single photons .What you refer to as the energy is the "Cumulative energy" of a continuous series of photons that lasts one second. The felt power of a one photon depends on the time it takes for one photon to deliver it's energy . Thus short wavelengths have more felt power ,and long wavelengths have less felt power . But both short and long wavelength photons both have the same energy , 6.626x10^-34 J
Photons don't have cycles. Only the averages of large numbers of photons can have wave properties.
@@schmetterling4477 and yet single photon experiments have been done where wave properties are exhibited
I just knew organic chemistry was going to help me out. My professor sucks fr
hey I ve a question . you guys using calculators to solve this kind of questions?
I love you
When your school teacher fails to teach you properly after having a PHD and 30+ years of teaching experience, you end up here.
What is the frequency of a 72 keV x-ray photon?
Photons don't have frequencies. Only the average of many photons (aka light) can have a frequency (and even that is the wrong way of looking at it - light doesn't have one frequency, it has a spectrum).
Thanks 😀 men and
God bless you.
How do you get that correct exponent? When I enter into a calc it gives me 33 or whatever not -19
Unless the plank constant has nothing to do with any mass, you can never apply that formula to find energy carried by photons
Can someone PLEASE explain how he got 1.82
How did you multiply #3 with 5mole multiply with Avogrado's number and the initial energy 8.28x10^-19? I couldn't get it on calculator.
No
Where are you gettin the numbers from
Look man, I love your stuff your really helping me through college. But your loading screen pics have the equation that I actually need, but then you load the video and its no where in there unless i have to painstakinglty watch you go over it. Please, im begging you to write them out in the begining or end of your video next time.
But why the powers are not correct
Sir, I need help figuring out hour to start out the problem: How much energy would be required to melt 10,700 g of ice?
I don’t know how to even start it! Can you explain what I must do in order to solve this problem
Ew ugrhg math 2 hard 4 me
This channel is really wonderful
Thanks so much 🔥🔥🔥🔥
i thought its physics not chemistry- ahhhhhh!! omg omg confusing
