If 12 g of C is burnt in the presence of 32 g of ${{O}_{2}}$

If 12 g of C is burnt in the presence of 32 g of ${{O}_{2}}$, how much C02 will be formed?

$C{{O}{2}}$ is formed by the following reaction,
C + ${{O}
{2}}$ ---------------> CO2

By the law of conservation of mass,
Total mass of reactants = Total mass of products Mass of C + Mass of 02 = Mass of $C{{O}{2}}$
12g + 32g = 44g
Therefore, 44 g of $C{{O}
{2}}$ will be formed.
