Zn + 2HCl ==> H2 + ZnCl2
mols HCl used = M x L = ?
Using the coefficients in the balanced equation, convert mols HCl to mols Zn.
Then mols Zn = grams Zn/atomic mass Zn. You know atomic mass and mols Zn, solve for grams Zn.

Zn + 2 HCl ---> ZnCl₂ + H₂
so .1 moles of HCl reacts with .05 moles of Zn
molar mass of Zn is 65.38 g
.05 * 65.38 = ?
