Calculate the mass of salt in the solution obtained by dissolving zinc in 73 g of 10% hydrochloric acid solution.

Zn + 2HCl = ZnCl2 + H2
the mass of the substance itself hydrogen chloride is 73 * 0.1 = 7.3 g
amount of hydrogen chloride substance = 7.3 / 36.5 = 0.2 mol
amount of salt substance = 0.2 / 2 = 0.1
mass of salt = 0.1 * (35.5 * 2 + 65) = 136
