Zn + 2HCl ==> H2 + ZnCl2
mols Zn = 4 from the problem.
Using the coefficients in the balanced equation, convert mols Zn to mols H2.
That's 4 mols Zn x (1 mol H2/1 mol Zn) = 4 mols H2.
1 mol H2 occupies 22.4 L at STP; therefore, 4 mols will occupy 4 mols x 22.4 L/mol = ?
grams = mols x molar mass = ?
