Question

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

Answer 1

Answer:

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.
