m(ppa NaOH) = 100 g
W(NaOH) = 14%
------------------------
m(CH3COONa)-?
m(NaOH) = m(ppa NaOH) * W(NaOH) / 100% = 100 *14% / 100% = 14 g
CH3COOH+NaOH-->CH3COONa+H2O
M(NaOH) = 40 g/mol
n(NaOH) = m/M = 14 / 40 = 0.35 mol
n(CH3COONa) = n(NaOH) = 0.35 mol
M(CH3COONa) = 82 g/mol
m(CH3COONa) = n*M = 0.35 * 82 = 28.7 g
ответ 28.7 г
