When carbon is burned in air carbon iv oxide gas is formed.

C (s) + O2 (g) = CO2 (g) ΔH = - 393.5 kj/mol

The enthalpy change of the reaction is - 393.5 j/mol which means that when one mole of carbon is completely burnt in air then 393.5 j of energy is evolved.

Thus, 1 mole = - 393.5 j, then for 480 kj

= 480 * 1/393.5

= 1.2198 moles

1 mole of carbon iv oxide is equal to 44 g

thus, 1.2198 moles will be 1.2198 * 44 = 53.6712 g of CO2
