Copper Sulfate + Ammonia

Copper Sulfate + Ammonia ➜ Tetra-amminocopper(II)sulfate
CuSO₄ + 4NH₃ ➜ Cu(NH₃)₄SO₄

CuSO₄ = 63.6+32.1+64 = 159.7 g/mol
4NH₃ = 4•14.01 + 12•1.008 = 68.14
Cu(NH₃)₄SO₄ = 63.6 + 4•14.01 + 12•1.008 + 32.1 + 4•15.99 = 227.84 g/mol

159.7 g of CuSO₄ + 68.14 g of NH₃ ➜ 227.84 g of Cu(NH₃)₄SO₄
