You burn 6 grams of carbon in plenty of air: C ( s ) + O 2 ( g ) → CO 2 ( g ) What volume of oxygen at rtp will be used up?

C ( s ) + O 2 ( g ) → CO 2 ( g ) From the reaction, it is clear that one mole carbon burns with one mole of oxygen to give one mole of carbon dioxide. Number of moles of 6 grams of carbon is 6 g 12 g = 0 . 5 mol Therefore 0 . 5 mol of carbon will burn with 0 . 5 mol of oxygen. Since, the molar volume of any gas at rtp is 24 dm 3 . Therefore, the volume of 0 . 5 mol of oxygen gas is 0 . 5 mol × 24 dm 3 = 12 dm 3
