The overall equation for the formation of hydrated copper (II) sulfate crystals from
copper (II) oxide is
CuO(s) + H2SO4(aq) + 4H20(l)→ CuSO4.5H.0(s)
(1) In an experiment, a student completely reacts 9.54 g copper(II) oxide.
Show that the maximum possible mass of CuSO4.5H20 crystals that can be
obtained is about 30 g
[Mr of CuO = 79.5 Mr of CuSO4.5H30 = 249.5)
