The interaction of 130 g of zinc with hydrochloric acid yielded 33.6 hydrogen.

The interaction of 130 g of zinc with hydrochloric acid yielded 33.6 hydrogen. What is the yield of hydrogen from the theoretically possible?

To obtain zinc chloride, metallic zinc can be dissolved in hydrochloric acid.

In this case, hydrogen will be released:

Zn + 2HCl → ZnCl2 + H2;

The molar amount of zinc will be equal to the molar amount of hydrogen.

Find the molar amount of zinc.

M Zn = 65 grams / mol;

N Zn = 130/65 = 2.0 mol;

Let’s calculate the volume of 2 mol of hydrogen.

The yield of hydrogen from the theoretically possible is 33.6 / 44.8 = 0.75 = 75%;
