(A) According to Graham's law of diffusion,the rate of diffusion $r$ is inversely proportional to the square root of the molar mass $M$: $\frac{r_A}{r_B} = \sqrt{\frac{M_B}{M_A}}$ Given: $M_A = 100 \ g/mol$ $M_B = 64 \ g/mol$ $r_A = 12 \times 10^{-3} \ mol/s$ Substituting the values: $\frac{12 \times 10^{-3}}{r_B} = \sqrt{\frac{64}{100}}$ $\frac{12 \times 10^{-3}}{r_B} = \frac{8}{10} = 0.8$ $r_B = \frac{12 \times 10^{-3}}{0.8} = 15 \times 10^{-3} \ mol/s$
