1. 2.5 mol Zn and 8.75 mol HCl react according
to the equation
Zn + 2 HCl −→ ZnCl2 + H2 .
Calculate the amount in moles of ZnCl2
formed.

2. mols AgNO3 = M x L = ?
Using the coefficients in the balanced equation, convert mols AgNO3 to mols NaCl.
Now convert mols NaCl to grams. g = mols x molar mass.

3. Your second problem is a limiting reagent (LR) problem. You know it is a LR problem because amounts are given for BOTH reactants. You do these just like simple stoichhiometry problem BUT do it for EACH reagent then take the smaller amount formed as the product formed.
Convert mols Zn to mols ZnCl2.
2.5 mol Zn will give you 2.5 mol ZnCl2 (1:1 ratio in the equation) if you had HCl in excess.
Do the same for HCl. 8.75 mols HCl will form 1/2(8.75) = 4.375 mols ZnCl2 if you had Zn in excess.
The smaller number is 2.5; therefore, 2.5 mols Zn will be formed, Zn is the limiting reagent, and HCl will be in excess which means some of it will react and there will be some left over.
Then convert 2.5 mol Zn to grams. g = mols x molar mass.
