1. Photon336

Here it is

2. Photon336

$Pv = nRT$

3. Photon336

yeah pressure and volume are the same and temperature

4. Photon336

$\frac{ 1 mol }{ 22.4L }$ at STP

5. Photon336

yeah, that's what I thought (the answer choice can't determine) is almost always WRONG lol

6. Rushwr

aren't they the Saeme

7. Empty

Yeah they are :)

8. Rushwr

same*

9. Empty

Hmm my answer accidentaly got deleted

10. Photon336

how did that happen?

11. Rushwr

$n=\frac{ NO. of molecules }{ Avagadro }$

12. Rushwr

substitute that in to PV=nRT

13. Rushwr

and get the number of molecules. Since they have the same pressure same temperature + universal gas constant and avagadro no. it should be same is what i thought. But I also have a gut feeling if it is the 2nd answer. More H molecules

14. Photon336

$H _{2}$ $O _{2}$ i feel like they are both diatomic molecules so it might be the same if we had the same temperature pressure and volume that's what I was thinking when I did this

15. Rushwr

16. Empty

It should be D if we are allowed to assume that both gasses are ideal gasses

17. Photon336

so why wouldn't we be able to determine number of molecules it?

18. Rushwr

wt is the answer given ?

19. Photon336

the answer is (C) they have the same number of molecules.

20. Photon336

g2g but I will post more questions tomorrow for sure.

21. Rushwr

okai!!!!!!!!!!

22. Empty

Oh I don't know why I said D I meant to say C haha
