m(CuSO4) = 10 g
m(KOH) = 10 g
----------------------------
m(Cu(OH)2) =?
M(CuSO4) = 160 g/mol
n(CuSO4) = m/M = 10 / 160 = 0.0625 mol
M(KOH) =56 g/mol
n(KOH) = m/M = 10 / 56 = 0.18 mol
n(CuSO4) < n(KOH)
CuSO4 + 2KOH-->Cu(OH)2+K2SO4
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 гр
