What mass of salt can be obtained if zinc with an amount of 0.4 mol

What mass of salt can be obtained if zinc with an amount of 0.4 mol of a substance is acted upon with chloride acid until it is completely dissolved?

The reaction between zinc and hydrogen chloride is described by the following chemical reaction equation.

Zn + 2HCl = ZnCl2 + H2;

1 mole of metal reacts with 2 moles of acid. In this case, 1 mol of salt is synthesized and 1 mol of gaseous hydrogen is released.

When 0.4 mol of metal is dissolved, 0.4 mol of its chloride is synthesized.

Let’s calculate the mass of salt.

M ZnCl2 = 65 + 35.5 x 2 = 136 grams / mol;

m ZnCl2 = 136 x 0.4 = 54.4 grams;
