Calculate the amount of carbon dioxide that could be produced when (i) 1 mole of carbon is burnt in air. (ii) 1 mole of carbon is burnt in 16 g of dioxygen. (iii) 2 moles of carbon are burnt in 16 g of dioxygen.
. 1 mole of Carbon burnt in air C + O2 →CO2 1 mole of carbon produces 1 mole of CO2 which is 44g of CO2 1 mole of carbon is burnt in 16g of dioxygen 32g of O2 = 44g of CO2 1g of O2 = 44/32 CO2 (Dioxygen is limiting reagent) 16g of O2 = 4/32 × 16 = 22g of CO2 in one mole 3) 2 moles of Carbon burnt in 16g of dioxygen 16g of dioxygen is available, and thus it can combine with 0.5 mol of carbon to give 22g of CO2
