A) 72
B) 6
C) 24
D) 36
Correct Answer: A
Solution :
Given, \[\frac{^{r}{{H}_{2}}}{^{r}A}=6,\,\,{{M}_{{{H}_{2}}}}=2,\,\,{{M}_{A}}=?\] From Grahams law of diffusion, \[\frac{^{r}{{H}_{2}}}{^{r}A}=\frac{\sqrt{{{M}_{A}}}}{{{M}_{{{H}_{2}}}}}\] or \[6=\frac{\sqrt{{{M}_{A}}}}{2}\]or \[36=\frac{{{M}_{A}}}{2}\]
