Reacts with what? I'll assume HCl but it could be anything.
1. Write the equation.
Zn + 2HCl ==> ZnCl2 + H2
2. Convert 25.0 g Zn to moles. moles = grams/molar mass.
3. Using the coefficients in the balancd equation, convert moles Zn to moles H2.
4. Now convert moles H2 to L.
L = mols H2 x (22.4 L/mol) = ??
