m(CuSO4) = 10 g
m(NaOH) = 10 g
--------------------
m(Cu(OH)2)-?
M(CuSO4) = 160 g/mol
n(CuSO4) = m/M = 10 / 160 = 0.0625 mol
M(NaOH) = 40 g/mol
n(NaOH) =m/M = 10 / 40 = 0.25 mol
n(CuSO4) < n(NaOH)
CaSO4+2NaOH-->Cu(OH)2+Na2SO4
n(CuSO4) = n(Cu(OH)2) = 0.0625 mol
M(Cu(OH)2) = 98 g/mol
m(Cu(OH)2) = n*M = 0.0625 * 98 = 6.125 g
ответ 6.125 g
