What mass of copper can be obtained as a result of the substitution reaction

What mass of copper can be obtained as a result of the substitution reaction between copper oxide 2 and hydrogen, with a volume of 4.48 liters?

The reduction reaction of copper oxide with hydrogen occurs in accordance with the following chemical reaction equation:

CuO + H2 = Cu + H2O;

1 mole of copper oxide reacts with 1 mole of hydrogen. This forms one mole of metallic copper and 1 mole of water.

Let’s calculate the chemical amount of a substance contained in 4.48 liters of hydrogen.

One mole of gas under normal conditions fills a volume of 22.4 liters.

N H2 = 4.48 / 22.4 = 0.2 mol;

The same amount of copper will be obtained. Let’s define its mass.

M Cu = 64 grams / mol;

m Cu = 64 x 0.2 = 12.8 grams;
