Identical rigid vessels contain two different ideal gases as shown below. Vessel 1contains pure gas A; while vessel 2 contains pure gas B; The molecular weight of A is twice

that of B. If the pressures in vessels 1 and 2 are equal (P1 = P2) and gas temperatures invessels 1 and 2 are equal (T1 = T2), what can be said about the molar densities(gmoles/volume) of gas in the two vessels if both gases can be assumed ideal? O The molar density in vessel 1 is half the density in vessel 2 O The molar density in vessel 1 is twice the density of vessel 2 Nothing can be said about density O The molar density of the two gases can never be equal Both have the same molar density since temperature and pressure are the same.
