CaO + H2O = Ca(OH)2
0.6 x
1 mol CaO ............ 1 mol Ca(OH)2
0.6 moli CaO ................ x
Obtinem x = 0.6 moli Ca(OH)2
1 1
Ca(OH)2 + CuSO4 = Cu(OH)2 + CaSO4
0.6 0.6
Analog si obtinem 0.6 moli CuSO4.
m CuSO4 = 0.6 * 160 = 96g CuSO4.
m sol CuSO4 = 100/20 * 96 = 480 g sol.
Raspuns : 480 g solutie.
