Zn + 2HCl ==> ZnCl2 + H2
mols Zn = grams/atomic mas = ?
Using the coefficients in the balanced equation, convert mols Zn to mols HCl needed. You can see 1 mol Zn uses 2 mol HCl so mols Zn x 2 = mols HCl needed.
Convert mols HCl needed to grams HCl by grams = mols HCl x molar mass HCl. Then since it is only 10% HCl you will need 10x that.
