Examples and practice problems of solving equation stoichiometry questions with gases. We calculate moles with 22.4 L at STP, and use molar mass (molecular weight) and mole ratios to figure out how many products or reactants we have.
it's a fact, just memorize it right now and you'll never forget it! at 0ºC and 1 atm pressure (this set of conditions is called "STP" for standard temperature (0º C) and pressure (1 atm)), 1 mole of ANY gas takes of 22.4 L. so anytime you're at STP and you have to go from liters to moles, you use 22.4.
dude ik this was 8 years ago but tysm for teaching me chemistry wayyy betterthan my teacher at school does!
Dude ik this was 11 years ago but thank you such much for teaching this. This is wayyy better than how my teacher explains it
Chem honors strugglers where we at
AP strugglers where we at
@@Viperzzzzzz right here 😭😭
Sana ol honor
@@Viperzzzzzz i am in your position but a year later lol, i am getting taught this in the first semester of regular chemistry ooooooooof
Ayyyy
My chem teacher doesn't even teach. she literally just puts this guy on and then goes to chill
yes
Probably for the best. I think the general consensus is most chem teachers suck (mine included).
I am doing an online chem course through the community college and this is EXACTLY what they do and charge 300 for the course.
I wish this guy was my chemistry teacher instead of the crappy one I have in school
Ikr tell me about it
Sally May I can relate. I have no idea what i'm doing rn and my project is due tomorrow :v
Please don't hate ur teacher. It will just make things worse.
There was a time that I hated my maths teacher.
After a while I started to understand why my marks were lower than 50%
So I made up my mind and started a new life in mathematics .... U Will Get To Know What Will Happen If You Try !
JUST ONCE!!
Sally May Me toooo
Sally May say bibe
I am shocked at how fast i went from not understanding in 2 hrs of class and then understanding after coming to the great Tyler DeWitt for help, for 9-10 mins. Thank you!
I still can't seem to understand this stoichiometry
i just had an epiphany.....you are Fred from Scooby Doo
so true
Whats an epiphnay
@@sobiataqi1810 sudden realization
I see it
Tyler,
Keep doing what you're doing. I'm a high school junior taking chemistry honors and your stuff has helped tremendously. It'd odd to see you teach the concepts so easily that I understand them and yet experience a brick wall type of teacher at school.
Congrats on 100,000 subscribers!
+Nick Epperson i am a sophmore taking honors chemistry and my teacher is confusing as hell.
Im a freshman taking honors chem and I just forgot to read the textbook like I was supposed to for hw. We have a test next week on this and 7 other topics. xC
Shalom A in real life in a 8 grader taking chemistry
Nick how is life going
@@brandontorres9181 I'm a sophomore taking honors chemistry too, just in 2024.
When he teaches better than your chemistry teacher
I'm so glad Eric from that 70's show decided to be a UA-cam chemistry teacher. He really helps me to learn
j. Stevens same man
so rude!! !
who would I be without this man. Wish I took his class lol.
your tutorials have saved me from failing honors chemistry
We are on the same boat...
Honors chemistry is harder than college
You are the best teacher ever! respects
spent 3 hours trying to figure out my problem set... this guy cleared it up for me in the first 3 minutes of the video
Thanks I watched this instead of studying and got an A- so that's pretty good!
I just have to say this: thank you so much, Tyler. Your videos have helped me countless times; your way of teaching is effective. You are so great at what you do; I hope that you keep making videos because they are among the highest quality on the internet for what they do.
Hey everyone, I'm here to help. If you have any questions or just want to learn more, click on the link in the description above. It'll take you to a page where you can ask me questions.
Thanks for showing that you could have two conversions. I knew that, but when I saw it visually in this video, it made conversion easier. Everything just made sense. Thanks again
You are flooded with compliments, but I thought I would add one more... You are so wonderful at explaining these equations in a comprehensible way. Thank you!
Best Chem teacher, mine just explains so fast and I hardly listen to him. You are the best chem teacher I ever seen and showed every step nice and slowly.
Thank you very much, you're helping my entire class pass..
Did they pass?
Tyler!
thank you so much for doing these videos!
they are so helpful! my teacher does not do a great job of explaining these things in terms that everyone can understand so when I found your videos I was so happy because I actually learned how to do these problems and understand chemistry.
I love how you taught this. Really appreciate it! Great teaching/tutoring!
Sir! I don't expect this much of excellency. Your path of teaching is really that I can't express by word's. May ALMIGHTY strengthen along your journeys. .
Your level of patience is remarkable.
Thank you sooo much!!! I spent about an hour or two watching ur videos and got a 93 on my exam
Thank you so much. I like that you go step by step with detail!
Thank you so much for doing these videos! They make everything seem much easier.
This video is amazing and it’s so helpful that you fully explained your process.
YOU ARE THE MAN, THE MYTH, THE CHEMISTRY LEGEND!
Hey Tyler, You're the most thorough teacher, and you make things so simple. Thank you. Your videos aren'ton Socratic anymore. Where can we find them all now?
when everyone else is struggling in chem honors but im in regular dying
This helps me so much. Way better than how my chemistry teacher explains in a 2 hour lecture
This really helped me with understanding my homework and recent labs , thank you !
you are saving me from failing honors chem. thank you for everything you do.
Out of all the videos I watched u explained it the best thanks
A great teacher you are. Thank you
You my good sir have won a new subscriber, keep it up man
Ty! Sir. I've learned a lot from watching your tutorials. Continue to do the good work 👍
It helped so much. Thanks for helping me review for my chemistry final.
Starting my day with coffee and Tyler DeWitt chem videos. Nothing beats this
Helping me pass my classes... Thank you so much!
Tyler- Great explanation. Thank you for posting
OMG why do I even go to lecture when you make my life 100 % easier lol Thank you!
u are so helpful! better than my teachers at school!
You saved my marks Tyler.. Thank you
Liters to moles
Moles to moles
Moles to grams
Kevin Nguyen YES
School starts tomorrow. I am entering grade 12 and thanks to you and a great teacher at school, I managed to get 86 in grade 11 chemistry. Thanks you sir.
Very helpful!! Can't even remember any word my teacher said. Then here's this helpful video. :D
nice video you have made my day TYLER
i Love you!!!! You make Chemistry so easy!
thank u so much for all the videos you've made. Really helped a lot :)
the best Chemist tutor
You're such a great explainer!
Bro I swear i love you so much
Thxs this video is really helpful due to all this digital learning
this man saving my chemistry mark
This guy is my favorite chem teacher now.
You are such a good teacher !!!!
Hi Tyler. I appreciate your great efforts. Good teacher. Thank you so so much..
Thank You man i understand this better now. I really appreciate it.
Time to work my ass for this term, love ur videos
You are the best I got a 97 last semester in preap chem and you helped me som much
im here because i have my o levels in a few months and this guy helps ALOT no joke
best teacher ever
WOW! you are a GREAT teacher! I wish my teacher was as good as you -____- thank you soooo much for making this video!
YOU ARE MY CHEMISTRY TEACHER NOW!
Man you help out so much you make me hate chemistry a little less
Thanks alot man, great video.
you are great, keep it up. Good work
Your videos are really good mate , just a quick question. On this stoichiometric equation ( and out of interest all others) do you not times the moles by 36 ( molar mass ) because there are 2 moles of it ?
Or do you just times it by the molar mass of one mole an all problems ?
Hey, thanks man; I appreciate it.
Thank you Mr DeWitt, it finally makes sense :D
Dude, i enjoyed ur videos, ur body languages are also very impressive, ty, and more videos to come
This guy is a legend
Sir ! I would love to know more about your site. Thank You sir
You are 100 times better than my teacher 🤗
Tawar Sardar even mine
We can express your opinion in the following two ways:
1 Tyler DeWitt/100 your teachers; or 100 your teachers/1 Tyler DeWitt
Is the equation you started with usually given or is that something you have to find out for yourself? If the second part is true, can you make a video just for that?
god bless ur soul u saved my life thank you tyler❤️
If only all teachers were like you...
Where are you getting the equations from? Where are 22.4 L and 18g coming from?
Hey I have a quick question for you, how did you get that 1 mole is 22.4 at stp?
Wow amazing ♥️
you saved my life
I freaking love you man
This is gonna help me so much for my quiz tomorrow. 😫
thank you sooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo much for your helpful videos
U make concepts more easier
Anisha Dhankhar 🗿🗿
I love you for this video

You are a great man :')
I love you, thankyou so much!!
U r a fine teacher
Thank you man thank you
Me: *studying*
Me to brain: FOCUS
Brain: looks like he has no fingernails
I can't unseee T-T
Thank you Tyler 😗😌
THANK YOU SO MUCH I FEEL CONFIDENT ON MY TEST NOW A+++++
How did you figure out the balanced equation
helps a lot!!!
upvote if you are a highschooler who just wants to enjoy dank memes and not have to worry about getting into college
+Miner Bryce You're gonna have a tough life lmao.
Better change your attitude bud, once your parents kick you out of their house, the real world is gonna bite you in the ass, just sayin.
And I do agree with your comment, worrying about college sucks but we have no choice..
Okay, I'll look forward to seeing you take my order at McDonald's in 10 years when you're living paycheck to paycheck living in some small dirty apartment.
you forgot about communism the perfect society
