m(CH3COOH) = 2.4 g
m пр (CH3COOCH3) = 3.7g
η(CH3COOCH3)-?
CH3COOH+CH3OH-->CH3COOCH3+H2O
M(CH3COOH) = 60 g/mol
n(CH3COOH) = m/M = 2.4 / 60 = 0.04 mol
n(CH3COOH) = n(CH3COOCH3)= 0.04 mol
M(CH3COOCH3) = 74 g/mol
mтеор (CH3COOCH3) = n*M = 0.04 * 74 = 2.96 g
η(CH3COOCH3) = mеор(CH3COOCH3) / m пр (CH3COOCH3) * 100%
n(CH3COOCH3) = 2.96 / 3.7 * 100% = 80%
ответ 80%
