Question

1 dm³ of hydrogen at S. T. P weighs, 0•09g. If 2 dm³ of a gas at S. T. P. weighs 2•880 g. Calculate the vapour density and the molecular weight of the gas​

Answer 1

Explanation:

vapour density of a gas= mass of a certain volume of gas at STP/mass of the same volume of hydrogen atSTP= 2.880/2×0.09= 16

and molecular weight of gas= 16×2 = 32 u
