Calculate the molar mass of a gas if 0.805g of this gas has a pressure of 4.00 bars at 305K in a 1 L. What is the gas density at this T and P, and what is the density at STP

gas density= mass/volume for the first case, both are given.
PV=nRT= mass/molmass*RT
solve for molmass, you are give all else
AT stp, you know T, P, n solve for new V
then gas density = mass/newvolume
PV=nRT= mass/molmass*RT
solve for molmass, you are give all else
AT stp, you know T, P, n solve for new V
then gas density = mass/newvolume
