Vapour density of a compound is defined as the ratio of mass of a certain volume of gas to the mass of the same volume of hydrogen gas under conditions of temperature and pressure. Vapour density=("Mass of certain of gas"(22.4L)"atSTP")/("Mass of same volume of" H_(2) "gas"(22.4L)"at STP") =(Mw)/(2) i.e., Molecular mass of gas=Vapour density xx2 Vapour density is a unitless quantity it is unaffected by variation of temperature and pressure. Let NH_(4)HS(s)hArrNH_(3)(g)+H_(2)S(g) The vapour density of the mixture will be:

1.	Vapour density of a compound is defined as the ratio of mass of a certain volume of gas to the mass of the same volume of hydrogen gas under conditions of temperature and pressure. Vapour density=("Mass of certain of gas"(22.4L)"atSTP")/("Mass of same volume of" H_(2) "gas"(22.4L)"at STP") =(Mw)/(2) i.e., Molecular mass of gas=Vapour density xx2 Vapour density is a unitless quantity it is unaffected by variation of temperature and pressure. Let NH_(4)HS(s)hArrNH_(3)(g)+H_(2)S(g) The vapour density of the mixture will be:
Answer» equal to that of `NH_(4)HS` LESSER than that of `NH_(4)HS` greater than that of `NH_(4)HS` cannot be PREDICTED. Answer :B
