Q. 7.5 grams of a gas occupy 5.6 litres of volume at STP. The gas is (Atomic weights of C, N and O are 12, 14 and 16 respectively)

States of Matter

Solution:

$5.6 \,L$ of a gas at STP weights $= 7.5\, g$
$22.4\, L$ of a gas weights $=\frac{22.4\times7.5}{5.6}=30\,g$
$\therefore $ Molecular weight is 30 g and the gas is $NO$.
