Vapour density of a compound is the ratio of mass of a certain volume of gas to the mass of same volume of hydrogen gas at same \( P \) and \( T \). This revels that molar mass of a gas \( = \) Vapour density \( \times 2 \). This formula is a valid only for gaseous state.
The vapour density of \( \mathrm{NH}_{4} \mathrm{HS} \) in its equilibrium mixture \( \mathrm{NH}_{4} \mathrm{HS}(V) \rightleftharpoons \mathrm{NH}_{3}(g)+\mathrm{H}_{2} \mathrm{~S}(g) \) at equilibrium is :
(A) \( 25.5 \)
(B) \( 25.5 \)
(C) \( 25.5 \)
(D) \( 51 \)
