Question

0.75 g of a gas occupy a volume of 300 ml at 650 mm Hg pressure and 25. If 100 ml
of hydrogen at STP weigh 0.009 g, calculate the vapour density of the hydrogen.

Answer 1

Explanation:

0.75g of a gas occupy a volume of 300ml at 650mmHg pressure and 25°C. If 100 ml of hydrogen at S.T.P weighs 0.009g. Calculate the molecular
