what is the Molecular equation for the preparation of tetra-aminocopper(II)sulfate hydrate - Cu(NH3)4SO4*H20

in the experiment CuSO4*5H20 was added to water and then ammonia solution was added to that. and then after that was all stirred up nicely 95% ethanol was added to the mix. im just really confused on where to get my molecular equation from
