Question

Calculate the mass of graphite that must be burnt to produce 13.2 gram of carbon dioxide

Answer 1

Explanation:

C +O2 =>CO2. So when one mole of graphite reacts with one mole of oxygen it becomes one mole of carbon dioxide. So 13.2 grams of carbon dioxide means 13.2/(12+2×16) => 13.2/44 => 0.3 moles so 0.3 moles of graphite is required which means (0.3×12) =>3.6 grams of graphite is required to produce 13.2 grams of Carbon dioxide. Hope it helps you.
