    \[50\text{ }ml\] of hydrogen diffuses through small hole from a vessel in 20 min time. Time taken for \[40\text{ }ml\] of oxygen to diffuse out under similar conditions will be

    A)  12 min                       

    B)  32 min

    C)  8 min            

    D)  64 min

    Correct Answer: D

    Solution :

    \[\frac{{{r}_{{{H}_{2}}}}}{{{r}_{{{O}_{2}}}}}=\sqrt{\frac{{{M}_{{{O}_{2}}}}}{{{M}_{{{H}_{2}}}}}}\] \[\frac{{}^{50}/{}_{20}}{{}^{40}/{}_{t}}=\sqrt{\frac{32}{2}}\] \[\frac{t}{16}=4\] \[t=64\,\min \]
