Density of phosgene gas, COCl2(MM=99) ander a certain condition is 4.5g/L. What is the density if H2S gas(MM=34) under the same conditions?

The density of a gas under a certain condition is determined by its molecular weight. Since the molecular weight of H2S gas is 34 and the molecular weight of phosgene gas is 99, the density of H2S would be about 0.45 g/L under the same conditions as phosgene. This is calculated by taking the molecular weight of phosgene and dividing it by the molecular weight of H2S (99/34 = 2.9), and then dividing the density of phosgene by this number (4.5/2.9 = 1.55 ~ 0.45).
