Question

calculate volume of oxygen required to complete combustion of 0.25 mole of methane at STP

Answer 1

Answer:

Thus for 1 mole methane we need 2 mole of oxygen for complete combustion. Hence 0.5 moles of oxygen will occupy 22.4 L x 0.5 = 11.2 L. 11.2 L of oxygen is required for complete combustion of 0.25 mole methane at STP.
