Calculate Molar Mass of Gas: 0.6536 g/L @ 37C & 787 torr

[chemistry4all]

Calculate the molar mass of a gas that has a density of 0.6536 g/L at 37C and 787 torr. What do you think the?

My attempt:

I used n= PV/RT and calculated the number of moles to be 16.0548g/mol.

The second part is where I am confused. Anyone help?

Second part? Eh?

oops didnt finish the last sentence. It is "What do you think you think the molecular formula of the gas is?


I think its CH4 because that's the only molecule I can find that has a MM close to 16g.
