Solution

The correct option is D $50$ ml
The reaction is $2 H C l \to H_{2} + C l_{2}$

$2$ moles of $H C l$ gives one mole of hydrogen.

At STP, $1$ mole of any gas occupies $22.4$ L.

Thus, $44.8$ L of $H C l$ gives $22.4$ L of hydrogen.

When $100$ ml of hydrogen chloride is completely decomposed, the volume of hydrogen formed is $100 \times \frac{22.4}{44.8} = 50$ ml.
