How many liters of H2 gas can be produced at 0 ∘C and 1.00 atm (STP) from 48.0 g of Zn?

Question

Zn(s)+2HCl(aq)→ZnCl2(aq)+H2(g)

Answer 1

mols Zn = grams/atomic mass = ?
Using the coefficients in the balanced equation, convert mols Zn to mols H2.
Then convert mols H2 to L using mols H2 x 22.4 L/mol = ?L.
