Question

Assume carbon burns according to following equation : 2C(s) + O2(g) 2CO(s) when 12 g carbon is burnt in 48g of oxygen, the volume of carbon monoxide produced is _______ × 10–1 L at STP [nearest integer] [Given : Assume CO as ideal gas, Mass of C is 12g mol–1, mass of O is 16 g mol–1 and molar volume of an idal gas at STP is 22.7 L mol–1]

Answer: .

💡 Solution & Explanation

2C + O2  2CO 12 (LR is C) 48 1 mole 1.5 mole 0 (1.5 – 0.5) 1 mole 1.0 mole Mole of CO = 1 mole (VCO)at STP = 22.7 Lit = 227  10–1 Lit
