Question
Calculate the density of sulfur trioxide gas at 35 degrees celsius and 715 torr pressure.
I know that d=m/v = PM/RT. Im not sure how to set this up. I know the molar mass of sulfur trioxide is 80.0642 but im not sure if I need to use that.

P = 715 torr x (1 atm/760 torr) = ? atm
M = you have
R = 0.08206 L*atm/mol*K
T = (273 + 35) kelvin.

I got 2.98g/L. Is this correct?
