A) 49.2
B) 37.9
C) 41.6
D) 83.2
Correct Answer: B
Solution :
From Grahams law of diffusion \[\frac{{{r}_{x}}}{{{r}_{S{{O}_{2}}}}}=\sqrt{\frac{{{M}_{S{{O}_{2}}}}}{{{M}_{x}}}}\] \[\frac{1.3}{1}=\sqrt{\frac{64}{{{M}_{x}}}}\] \[\Rightarrow \] \[{{M}_{x}}=\frac{64}{1.3\times 1.3}=37.86\] \[=37.9\]You need to login to perform this action.
