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

Zn (s) + 2 HCl (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 of ZnCl2 is eventually isolated.

What is the composition of the brass by mass? (i.e., m%Cu, m%Zn)
