The molecular weight of carbon dioxide, co2, is 44.00 amu, and the molecular weight of nitrous dioxide, no2, is 46.01 amu, so no2 diffuses co2

Grahm's law of diffusion states that the rate of diffusion of a gas is inversely proportional to the square root of the mass of its particles.

Molecular weight of NO2 = 46 g mol¹-

Molecular weight of CO2 = 44g mol¹-

Thus the compound which has a lower molecular mass will diffuse at a faster rate than the heavier compound. In this case, the molecular mass of NO2 is more than the CO2 so, NO2 will diffuse at a slower rate than the CO2 molecule.
