2. CuSO4 + 4NH—>
Cu(NH3)4SOA
a. If you react 15 g CuSO, (MM-159.5 g/mol) and 6g NH, (MM-17 g/mol) determine
the mass of Cu(NH,),SO, (MM-227.5 g/mol) that should theoretically be produced.
(3 pts)
b. If 17 g of Cu(NH,),SO, is recovered experimentally, determine the % yield of the
product. (3 pts)
c. What mass, in grams, of the excess reactant is consumed (not how much is remaining
after) during the reaction? (3 pts)
