Determine the composition of the brass by mass

An alloy of Zn and Cu, reacts with hydrochloric acid as follows:

Zn (s) + 2HCl(aq) -----> ZnCl₂(aq) +H₂(g)

(Cu does not react with HCl) When 0.5065 g of a certain brass alloy is reacted with excess HCl, 0.0985 g is eventually isolated.

1. Determine the composition of the brass by mass?

2. Explain how could this result be checked without changing above practice?
