Question

I need help with finding the theoretical yield of Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g). So far I have 24.305 + 37.4688 = 61.7738 g based on the weight of MgCl2 + H2, but I'm not exactly sure what to do or if I've even started it properly. Also, if you could help me with the percent yield of that equation. Any help would be greatly appreciated.

Answer 1

Here is just what you need? This is a worked example of a stoichiometry problem.
