1.	One litre of a gas weighs 3.57 xx 10^-3 kg at N.T. P. The gas is ________ . ( C = 12, O = 16, S = 32)
Answer» Carbon monoxide Sulphur dioxide Sulphur trioxide Carbon dioxide Solution :(a) `(28)/(22.4) = 1.25 g =1.25 xx10^(-3)KG` (b) `(64)/(22.4) = 2.857g = 2.857 xx10^(-3) kg` ( C) `(80)/(22.4) = 3.57 g = 3.57 xx10^(-3) kg` (d) `(44)/(22.4) = 1.96 g = 1.96xx10^(-3) kg` The correct answer is ( c).
