| H2 + S = H2S

Let us find the amount of sulfur by the formula v = m / Mr, where m is the mass of the substance, v is the amount of the substance, Mr is the molecular weight.

Mr (S) = 32 g / mol

v = 16/32 = 0.5 mol

The equation shows that sulfur and hydrogen sulfide are in a 1: 1 ratio, therefore, the amount of sulfur is equal to the amount of hydrogen sulfide.

v (S) = v (H2S) = 0.5 mol

The volume of hydrogen sulfide is found by the formula V = v * 22.4, where V is the volume of the substance, 22.4 l / mol is the molar volume of gases.

V = 0.5 * 22.4 = 11.2 l

Answer: when 16 g of sulfur interacts, 11.2 liters of hydrogen sulfide are formed.
