Determine the volume of hydrogen sulfide obtained if 100 g of sulfur is consumed in the reaction

Determine the volume of hydrogen sulfide obtained if 100 g of sulfur is consumed in the reaction with hydrogen and the fraction of the reaction product yield from the theoretically possible is 80%.

Let’s implement the solution:

According to the condition of the problem, we will write the data:
S + H2 = H2S – compounds, hydrogen sulfide was formed;

Let’s make the calculations:
M (S) = 32 g / mol;

M (H2S) = 34 g / mol.

Determine the amount of the original substance:
Y (S) = m / M = 100/32 = 3.125 mol;

Y (H2S) = 3.125 mol since the amount of substances is 1 mol.

We find the volume of the product, taking into account its output:
V (H2S) = 3.125 * 22.4 = 70 l (theoretical volume);

V (H2S) = 0.80 * 70 = 56 l (practical volume).

Answer: the volume of hydrogen sulfide is 56 liters.
