What is the volume of hydrogen sulfide, which is formed by the interaction of hydrogen with sulfur

What is the volume of hydrogen sulfide, which is formed by the interaction of hydrogen with sulfur, if the mass of sulfur is 16 g?

Let’s write the reaction equation:

H2 + S (t) = H2S

Let’s find the amount of sulfur substance:

v (S) = m (S) / M (S) = 16/32 = 0.5 (mol).

According to the reaction equation, 1 mol of H2S is formed from 1 mol of S, therefore:

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

Thus, the volume of the formed hydrogen sulfide, measured under normal conditions (n.a.):

V (H2S) = v (H2S) * Vm = 0.5 * 22.4 = 11.2 (l).

Answer: 11.2 l.
