Answer
[By Gay Lussac's law]
2 Vol. of C2H2 requires 5 Vol. of oxygen
∴ 400 ml C2H2 will require x 400
= 1000 ml of Oxygen
Hence, required volume of oxygen = 1000 ml
Similarly,
2 Vol. of C2H2 produces 4 Vol. of Carbon dioxide
∴ 400 ml of C2H2 produces x 400
= 800 ml of Carbon dioxide
Hence, carbon dioxide produced = 800 ml
