Vedclass · Answer

(A) According to Graham's Law of Diffusion,the rate of diffusion of a gas is inversely proportional to the square root of its molar mass $(r \propto 1/\sqrt{M})$. Therefore,gases with the same molar mass will diffuse at the same rate. The molar mass of $CO_2 = 12 + (2 	imes 16) = 44 \ g/mol$. The molar mass of $N_2O = (2 	imes 14) + 16 = 44 \ g/mol$. Since both $CO_2$ and $N_2O$ have the same molar mass of $44 \ g/mol$,they will diffuse at the same rate.

The atomic masses of carbon,nitrogen,and oxygen are $12, 14$,and $16$ respectively. Which of the following pairs of gases will diffuse at the same rate?
