A mixture of 20 mL of CO , CH4 and N2 was burnt in excess of O2 resulting in reduction of 13 mL of volume. The residual gas was then treated with KOH solution to show a contraction of 14 mL in volume. Calculate volume of CO , CH4 and N2 in mixture. All measurements are made at constant pressure and temperature.
