Don't all ideal gases have the same volume at STP?

• Chemistry -

yes 1 atm right?

• CHEMISTRY -

No, I think that's 22.4 L for a mole. To answer the question, I think I would use PV = nRT and calculate the volume of each. 80 grams of each is not the same number of moles.

i think its 1atm as well

• CHEMISTRY -

ur all wrong
