What volume of gas is formed when iron is dissolved in 1168g of 25% hydrochloric acid solution?

The reaction of iron with hydrochloric acid is described by the following chemical reaction equation.

Fe + 3HCl = FeCl3 + 1.5 H2;

When 1 mol of iron is dissolved, 1.5 mol of hydrogen is released. This requires 3 mol of hydrochloric acid.

Determine the amount of substance contained in 1168 grams of 25% hydrochloric acid solution.

M HCl = 1 + 35.5 = 36.5 grams / mol;

m HCl = 1168 x 0.25 = 292 grams;

N HCl = 292 / 36.5 = 8 mol;

Reaction with 8 moles of hydrochloric acid with sufficient iron will produce 4 moles of hydrogen.

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

Let’s determine the volume of hydrogen.

V H2 = 4 x 22.4 = 89.6 liters;
