photon336 · Answer

Here it is

photon336 · Answer

$$Pv = nRT$$

photon336 · Answer

yeah pressure and volume are the same and temperature

photon336 · Answer

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

photon336 · Answer

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

rushwr · Answer

aren't they the Saeme

empty · Answer

Yeah they are :)

rushwr · Answer

same*

empty · Answer

Hmm my answer accidentaly got deleted

photon336 · Answer

how did that happen?

rushwr · Answer

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

rushwr · Answer

substitute that in to PV=nRT

rushwr · Answer

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

photon336 · Answer

$$H _{2}              $$
$$O _{2}$$
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

rushwr · Answer

what is the answer given?

empty · Answer

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

photon336 · Answer

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

rushwr · Answer

wt is the answer given ?

photon336 · Answer

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

photon336 · Answer

g2g but I will post more questions tomorrow for sure.

rushwr · Answer

okai!!!!!!!!!!

empty · Answer

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