NH4Cl ==> NH3 + HCl
mols NH3 produced = grams/molar mass = 134/17 = approx 8 but you need a better answer.

Using the coefficients in the balanced equation A(everything is 1:1) convert mols NH3 to mols NH4Cl.
Now convert mols NH4Cl to grams. g NH4Cl = mols NH4Cl x molar mass NH4Cl
Post your work if you get stuck.
