    Calculate Mass Percent of Cu & Zn in Brass Alloy

    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...
