I work these LR problems the long way.
CuCl + H2S --> Cu2S + 2HCl
mols CuCl = grams/molar mass
mols H2S = grams/molar mass
Using the coefficients in the balanced equation, convert mols CuCl to mols Cu2S.
Do the same for mols H2S to mols Cu2S.
It is likely that the values will not be the same for mols Cu2S which means one of them is not right. The correct answer in LR problems is ALWAYS the smaller value and the reagent producing that value is the LR.
