I usually don't comment on a lot of videos, but I have watched so many videos relating to chemistry-stoichiometry, and this, by far, is the only video that I was able to understand. I will definitely be watching the MCAT video playlist. Thank you!

No because I used to hate studying for this topic so much and I was pulling an all-nighter studying for this and your little comments have put a smile on my face THANK yOU SO MUCH MEDICOSIS

Your sarcastic tone at the beginning of this video was all I needed. This was fantastic, easy and it made so much sense. I wish you were teaching my chemistry class. I'll be coming back when I need more help. I am sure I'll need help in Biochem. Thanks so much. YOU ARE AWESOME!!!

18:23 is wrong as it only maintains 2 significant figures out of the three, therefore you must place it in scientific notation as 1.50 times 10 to the 2nd or add a dot at the end to make it 150.

Answer: 4Al + 3O2 -> 2Al2O3 2.50 grams of Al / 26.98 (molar mass of Al) = 0.09 , 0.09 moles of Al *( 3moles or O2 / 4 moles of Al)= 0.0694 moles of O2, 0.0694 * 32 (molar mass of O2) = 2.22 grams (3SF)

[@sayyaanaiza1018]

my answer in the problem given is 2.22 g of O2. is that correct?

[@ChristopherMurphy-ug6zf]

just want to confirm that there can be more than one answer to problems like the one at 22:50 since some videos on KZbin will have different molar masses for elements, for example the periodic table my professor gives us to refer to on exams has Hydrogens atomic mass being 1.01, and when I did the problem my total answer was 22.8g H2O not 22.7 since my Molar Mass for H2O is 18.02g ( 2(1.01)+16.00 = 18.02).

[@MedicosisPerfectionalis]

Yes, the number that you will use to calculate the molar mass will affect the final answer.

[@alexszerlip7032]

I got 2.22 for 25:14

[@mbaby1908]

[@alisej1773]

[@MedicosisPerfectionalis]

[@typical_chest8315]

hey, so for the mass to mole problem you did, I used 72 g of H20 over 160 g of 02 and then 1 mol of H20 over 18 g of H20 for the second step and got the SAME answer. Im pretty sure both ways work but im nto 100%

[@gwyom1a]

25:15 = 2.22 g O2
