Carbon dioxide and Nitrous oxide

Vedclass · Answer

(A) According to Graham's Law of Diffusion,the rate of diffusion $r$ is inversely proportional to the square root of the molar mass $M$ of the gas: $r \propto \frac{1}{\sqrt{M}}$.For two gases to diffuse at the same rate,they must have the same molar mass.Calculate the molar masses of the given compounds:$CO_2 = 12 + (2 	imes 16) = 44 \ g/mol$.$N_2O$ (Nitrous oxide) $= (2 	imes 14) + 16 = 44 \ g/mol$.Since both $CO_2$ and $N_2O$ have a molar mass of $44 \ g/mol$,they will diffuse at the same rate.

Given that the atomic weights of carbon,nitrogen,and oxygen are $12$,$14$,and $16$ respectively,which of the following pairs of gases will diffuse at the same rate?
