In excess of oxygen burned 16 g of sulfur, determine the amount of oxygen consumed.

1. The combustion of sulfur in oxygen is described by the equation:

S + O2 = SO2;

2. Let’s calculate the chemical amount of sulfur:

n (S) = m (S): M (S) = 16: 32 = 0.5 mol;

3. Set the amount of required oxygen:

n (O2) = n (S) = 0.5 mol;

4. Determine the volume of oxygen:

V (O2) = n (O2) * Vm = 0.5 * 22.4 = 11.2 liters.

Answer: 11.2 liters.
