How many grams of Ag2S react to form 174 g of AgCl? see below:

Ag2S + 2 HCl ==> 2 AgCl + H2S

label your problem using the right subject
175g AgCl x (1 mol/247.9g) x (1 Ag2S/2AgCl) x (143.4g/1 mol) = 50.615g Ag2S

I'm assuming you've learned about basic stoichiometry and how to use mole bridges? Otherwise this type of question wouldn't be asked.
