1.250g of an alloy which is 90.00% Ag and 10.00% Cu is dissolved in nitric acid yielding AgNO3 and Cu(NO3)2 solution. The nitrates are converted to Ag2SO4 and CuSO4 by heating with H2SO4. To the solution of the sulfates is added a piece of copper wire which reacts with the Ag2SO4 to precipitate all the silver. The reaction is: Ag2SO4 (aq) + Cu (s) > 2 Ag (s) + CuSO4 (aq). The resulting solution is treated with excess zinc to precipitate all of the copper (II) ion in the solution. What weight of copper will be precipitated?
