Question

Find the percentage composition by mass of each compound given: 
Raw Materials: 500 g calcium polysulphide and 1.5 kg hydrochloric acid 
Actual Yield: 343.4g precipitated sulfur



Whereas the balanced chemical reaction, as given in the problem, is: CaS5+2HCl => 4S + CaCl2 + H2S

I think for this solution, total mass should be calculated first. Please include the detailed solution whereas the units or label is present. Thank you so much for helping me out. I am sad.
