Solution

The correct option is B $35.5$ g $C l_{2}$ gas
$2$ g of $H_{2}$ gas has $1$ mole.
$22.4$ L of $S O_{2}$ gas at NTP has also $1$ mole.
$1$ mole $S O_{2}$ gas has already given $1$ mole.
$35.5$ g of $C l_{2}$ = $\frac{35.5}{71} = 0.5$ mole.
Hence chlorine has minimum number of moles and thus minimum number of molecules.
