Can you check my answer? Thank you
What is the molar mass of a gas that behaves ideally (i.e. obeys the perfect gas law pV=nRT) if it has a density of 1.92 g dm-3 at 150 kPa and 25 C?
I got;
M=p(density)RT/(P)=31.7 kg mol^-1

31.7 is ok but are sure that's kg/mol. The density is given in g/L. Besides, a molar mass of 31,700 for a gas seems unreasonably high to me.
