How many grams of solid zinc metal will completely react with 100.0 mL of 0.0525 M HCl, if zinc chloride and hydrogen gas are the only products?

3 answers

Zn + 2HCl ==> H2 + ZnCl2

mols HCl = M x L = ?
Using the coefficients in the balanced equation, convert mols HCl to mols Zn.
Now convert mols Zn to grams. g = mols Zn x atomic mass Zn.

0.172

1.72 g Zn
