Suppose 5g of calcium hydroxide and 10g of ammonium chloride are mixed in a test tube and heated unitl no more ammonia is given off. The remaining material in the test tube has a mass of 1.27g. What total mass of ammonia and water vapor was produced in the reaction?

You begin with 15g of reagents in your tube. You are left with 1.27g so the total mass of ammonia an water given off must be 15-1.27g[ Conservation of matter, a chemical reaction cannot create or destroy matter] You can do the sum
