m(CH3COOH) = 44 g
m(C2H5OH) = 52 g
-----------------------------
m(CH3COOC2H5)-?
M(CH3COOH) = 60 g/mol
n(CH3COOH) = m(CH3COOH) / M(CH3COOH) = 44 / 60 = 0.73 mol
M(C2H5OH) = 46 g/mol
n(C2H5OH) = m(C2H5OH) / M(C2H5OH) = 52 / 46 = 1.13 mol
n(CH3COOH) < n(C2H5OH)
M(CH3COOC2H5) = 88 g/mol
CH3COOH+C2H5OH-->CH3COOC2H5+H2O
n(CH3COOH) = n(CH3COOC2H5) = 0.73 mol
m(CH3COOC2H5) = n(CH3COOC2H5) * M(CH3COOC2H5)
m(CH3COOC2H5) = 0.73 * 88 = 60.59 g
ответ 60.59 г
