An amount of 1.250g of an alloy (90% Ag, 10% Cu) was treated withHNO3 and H2SO4 to form Ag2SO4 and CuSO4. The solution was then treated with Cu wire to precipitate silver. The resulting solution was treated with excess zinc to precipitate copper.
a. What mass of copper will be precipitated?
b. What total mass of zinc will be dissolved (neglect any dissolvedby excess H2SO4)?
