Professor Organic Chemistry Tutor, thank you for an outstanding video/lecture on the Law of Definite Proportions in AP/General Chemistry. The examples/practice problems show how to calculate the Law of Definite Proportions from start to finish. This is an error free video/lecture on UA-cam TV with the Organic Chemistry Tutor.
People used to extract silver atomic mass 108 from silver bromide, AgBr in X-ray photographs. If bromine has an atomic mass of 80 what mass of silver can u extract from 564g of silver bromide
A 22.7 g sample of CaSO4 is found to contain 6.68 g of Ca and 10.7 g of O. Find the mass of sulfur in a sample of CaSO4 with a mass of 72.4 g. Could somebody help me solve this?
Hi first you should Obtain the percentage of sulfur that makes up the first composition in terms of grams(23.56%) and then multiply this value by the second substance and you will have your answer(17.05 g) and the reason of multiplying is law of definite composition
Sir wt is the meaning of this . *Atoms combine in the ratio of small whole numbers to form compunds* From ncert 9th 3 Rd chapter sir. I dint get this plz can u tel me
It basically means how compounds are made; Compounds are basically formed when different atoms are combined, for example, h20, it's basically 2 (which is a whole number) atoms of hydrogen combined with 1 (again a whole number) atom of oxygen to form h20 (which is a compound)

Saving my GPA again. One of the best academic channels on youtube
This man has taught more people than a 100 mid-sized schools can in a century
Which grade were you back then
@@Phantom_Deluxe7 grade? I'm a college student.
@@notsam498 So u learning the laws of chemical combosition in college or you studied it before in any grade?
@@Phantom_Deluxe7 He is taking General Chem which is ap chem in 10th grade
You saved me from panicking about my grades. Now I understand this concept more thanks to your channel. It needs more recognition as a whole.
Took 2 minutes to teach me something that took my current teacher 4 hours. Thank you sir.

This helped me so much! Thank you!
Bro helps generationally
You make chemistry so easy ! May God always bless you.
True👏👏
People used to extract silver atomic mass 108 from silver bromide, AgBr in X-ray photographs. If bromine has an atomic mass of 80 what mass of silver can u extract from 564g of silver bromide
324g of Ag can be extracted from 546g of AgBr.
thank you .very helpful
Army lol!!
Very helpful , really Thanks so much
Thank you!!
I can't understand any of the channel s but I like this class and I understood what It is sir was saying 👍 and it was a good class

Thank you
Thank you for your help
We can take the ratio of 54:48 as 9:8
Thank you so much
Greatest Of All Time ❤🎉💯
@7:40 is it the same as 3gC=1gH?
Yeah its same as 3:1
Are we using a mole?
Thanks, u have saved me!
You are preparing me as I am writing my final high school leaving exams in Liberia
what software do you use
You are the BEST 🎉❤
oh i'm sorry disarranged the numbers that's why it results into 0.375 . coz insted of 32/12 i make it 12/32
Thank you very much

Hlooooooooooo ur helping me a lot.
What about 64/24
To hard for me 😭
too*
You got this!
Skill issue
where did you get the 36?
24+12=36
12x3
Thanks a lot you saved me from failing
Fantastic
Sir.May i know why grams is taken....,
where did you get 2.67 ? coz when i calculate 12/32 the answer is 0.375.
Iguess it is 32/12
Yes i already said that hehe .thanks
u should get 2.66666, but there r more no of 6 so they took 1 seven and ended the number .......
How did you get 80 g c
he multiplied 30 by 32 and then he divided by 12
Thank❤ this is very useful
@Alan P Aniyan yes
@Alan P Aniyan Aa padichu kurach
Ni padicho
29g F with proper sig figs
Where is law of reciprocal ?
Always here Sir
HEhe test 100/100!!
The sound is low, please make it high
Love u bro 💕💕💕💕💕💕❤❤❤❤
thx
U were using calculator 😅 but u teach so welll 👌💯
and is he supposed to be calculator??
Sir meaning to samjhae hii nhii
i just multiplied the 30 by 2.67 and got the same answer
*JG* nxt time don't use calculator pls do the problem!
It will be more useful :)
Done
Sir that is not mass that is unit(u)
in 3 question the answer is 21.75
No understand..🙄
i love you
The mass hydrogen is 2
No
😍😍😍😍
