The density of gas at non standard conditions is given by the formula:

d = PM/(RT)= 5.2g/L
R = 0.08205at-L-mol-1-K-1
M = molar mass or molecular weight
T = 273.15 + C = 508.15
P = 2.00 atmo

M = dRT/P (5.2 x 0.08205 x508.15)/2.00 = 108.4 g/mol
110 g/mol using significant figures.

Molecular weight may be the mass of a million molecule of the gas. you have solved for molar weight that's the mass of 6.022 x 10^23 molecules of the gas: Assuming STP (22.4L/mol)(2.18g/L)(1mol/6.022 x 10^23molecules) = 8,11 x 10^-23g/molecule

multiply the density times the gas constant R then times the temperature, then divide it all by the pressure. make sure your units cancel.
