If the profile pic is your real picture Then are you really learning this because I am 15 and I have this in my this year's course in India and you probably be like 19-21

@@narayanchandradas4602 rude giving (guessing) someone's age based on looks 😑 and every country has it's own educational system, common is we learn this in high school, doesn't matter which grade, and if you took it in middle school then probably that was just an intro and upper class's lessons are advanced btw, so why would you compare(or whatever you said)? 😐

Why are KZbinrs better than actual teachers? xD

because the youtuber has more time than the teacber.KZbinr doesnt have an environment where noise exists,so his explanation is more understandable than the teacher

[@tortul1462]

I have a formula for those who have hard time understanding the last part: Molar Mass of Molecule = (MM of Atom) x (No. of atoms) _______________________________ (Mass % of atom) ÷ (100%) *** In the example given in the video this'll be it: MM of molecule = (MM of Atom) x (No. of atoms) _______________________________ (Mass % of atom) ÷ (100%) = (14.01) x (1) __________________ (13.32%) ÷ (100%) = 14.01 ______ 0.1332 = 105.18 *** Additionally, to prove that it is actually the MM of the molecule, you divide the MM of the atom (which is the Nitrogent) divided by the MM of the molecule multiplied by 100%: Mass% of N = (14.01 ÷ 105) x 100% = 13.32%

I can add for you an short cut. I their was an 3 element, find 2 and minus the 2 element by 100. example: if the element 1 is 50 and the element 2 is 30. 100-50-30 so the third element will be 20%. These is an easy way by wasting non-wastable time in the exam. Regards, Ali from UAE.
