Calculate the mass of zinc chloride, which is formed by the interaction of 50g. zinc with hydrochloric acid.

We draw up the equation for the interaction of zinc with hydrochloric acid: Zn + 2HCl = ZnCl2 + H2.
Chorus of problem solving:
1) Determination of the molar mass of zinc according to the periodic table.
2) Calculation of the amount of zinc substance by dividing its mass by molar mass.
3) Determination of the amount of zinc chloride substance according to the reaction equation.
4) Finding the molar mass of zinc chloride.
5) Calculation of the mass of zinc chloride.
Decision:
1) 65.
2) 50/60 = 0.83 mol.
3) According to the reaction equation, one mole of zinc accounts for one mole of zinc chloride. This means that the amount of zinc chloride substance is 0.83 mol.
4) 65 + 35.5 * 2 = 136.
5) 0.83 * 136 = 112.88g – the answer.
