  • question_answer Two grams of hydrogen diffuse from a container in 10 minutes. How many grams of oxygen would diffuse through the same container in the same time under similar conditions            [MNR 1980]

    A)                 0.5 g     

    B)                 4 g

    C)                 6 g         

    D)                 8 g

    Correct Answer: A

    Solution :

               \[{{r}_{H}}=\frac{2gm}{10\min }\] if \[{{r}_{O}}=\frac{xgm}{10\min }\]            \[{{r}_{O}}={{r}_{H}}\sqrt{\frac{{{M}_{{{H}_{2}}}}}{{{M}_{{{O}_{2}}}}}}=\frac{2}{10}\sqrt{\frac{2}{32}}\]                                 \[\frac{x}{10}=\frac{2}{10\times 4}=\frac{1}{2}gm.=.5gm\]
