Question

When carbon reacts with 32 g of oxygen 44 g of carbon dioxide is formed The mass of carbon will be

Answer 1

22 g of CO2 will be formed when 6 g of carbon is burnt in 32 g of oxygen. The atomic mass of C is 12 g/mol. The molecular masses of O2 and CO2 are 32 g/mol and 44 g/mol respectively. 12 g C will combine with 32 g O2 to form 44 g CO2.
