उत्तर
Let the required time be t.
Mass of 1 litre hydrogen,
\[m = \frac{2}{22 . 4} g\]
Using the formula, m = Zit, we get:-
\[\frac{2}{22 . 4} = \frac{1 \times 5 \times t}{96500}\]
\[ \Rightarrow t = \frac{2 \times 96500}{22 . 4 \times 5}\]
\[ \Rightarrow t = 1723 . 21 s = 28 . 7\text{ minutes} \approx 29\text{ minutes}\]
