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 $M$: $\frac{r_1}{r_2} = \sqrt{\frac{M_2}{M_1}}$.For hydrogen gas $(H_2)$,$M_1 = 2 \ g/mol$.For helium gas $(He)$,$M_2 = 4 \ g/mol$.Substituting these values into the formula: $\frac{r_{H_2}}{r_{He}} = \sqrt{\frac{4}{2}} = \sqrt{2} \approx 1.414$.Therefore,the rate of diffusion of hydrogen gas is approximately $1.4$ times that of $He$ gas.
