Question

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 CH4 in mixture : (1) 40 (3) 60 (2) 20 (4) 50/////////give the correct answer opt

Answer 1

Explanation:
