Ideal Gas question

Members don't see this ad.

The volume of 1.00 mole of an ideal gas at 25'C, 1.00 atm is 22.4L

why is this false?

haha this question is evil, its 25 degrees celcius, thats wrong...its supposed to be 0 degrees celcius or 273 degrees kelvin...

STP = standard temperature and pressure, which is 1 atm, 273K/0C, and then you can say that its 22.4L

Other than that you cant say its 22.4L because the temperature is actually 298K which would increase the volume to a lil over 22.4L at 1 atm

Oh man, what a devious question. 25'C is about room temp. Just know the "T" in STP is in Kelvin, so 273K.......which is also = to 0'C.

hah! good catch, I hope I don't miss that one on the DAT!

How about this one, why is it false?

The volume of 1 mole of H2 gas is only 1/16th of the volume of 1 mole of O2 gas, at the same temperature and pressure.

isn't it because when you talk about volume, you only consider number of moles therefore doesnt really matter which

i know that if they asked about density instead of volume, the numbers would be different.

😕
