(C) According to Graham's Law of diffusion,the rate of diffusion $r \propto \frac{1}{\sqrt{M}}$,where $M$ is the molar mass.The molar mass of $NH_3$ is $17 \ g/mol$ and the molar mass of $CO_2$ is $44 \ g/mol$.Since $M_{NH_3} The ratio of their rates of diffusion is given by:$\frac{r_{NH_3}}{r_{CO_2}} = \sqrt{\frac{M_{CO_2}}{M_{NH_3}}} = \sqrt{\frac{44}{17}} \approx 1.61$.

Between $NH_3$ and $CO_2$,which one will diffuse faster? What will be the ratio of their rates of diffusion?
