2 Iron(III) oxide (Fe2O3) is reduced by carbon on heating to give iron metal (Fe) and
carbon dioxide (CO2). (Ar values Fe 56, C 12,0 16)
When 480 g of Fe2O3 is heated with carbon, 336 g of Fe and 198 g of CO2 are produced.

reacted.

Using the law of conservation of mass, the mass of carbon reacted is 54 g of carbon.

What is the law of conservation of mass?

According to the law of conservation of mass, matter is neither created nor destroyed. This means that the total mass of reactants is equal to the total mass of products.

Total mass of the products = 336g + 198g = 534 g

Total mass of reactants = 480 g + x g

From the law of conservation of mass;  534 g = 480 g + x g

x g = 534 g - 480 g

x g = 54 g

Hence, 54 g of carbon reacted.
