Ответ:
дано
m(ppa CH3COOH) = 60 g
W(CH3COOH) = 10%
-----------------------------
m(KOH)-?
m(CH3COOH) = 60 * 10% / 100% = 6 g
CH3COOH+KOH-->CH3COOK+H2O
M(CH3COOH) = 60 g/mol
n(CH3COOH) = m/M = 6 / 60 = 0.1 mol
n(CH3COOH) = n(KOH) = 0.1 mol
M(KOH) = 56 g/mol
m(KOH) = n*M = 0.1 * 56 = 5.6 g
ответ 5.6 г
