Zinc reacts with hydrochloric acid according to the following equation:

Question

Zn + 2HCl --> ZnCl2 + H2

If 3.63 grams of zinc react, how many grams of zinc chloride is produced?

Answer 1

Convert 3.63 g Zn to mols. mols = grams/molar mass.
Use the equation coefficients to convert mols Zn to mols ZnCl2.
Convert mols ZnCl2 to g. g = mols x molar mass.

Answer 2

490.05
