m(ppa CH3COOH) = 64 g
w(CH3COOH) = 60%
m(CH3OH) = 32 g
m(CH3COOCH3)-?
m(CH3COOH) = 64*60% / 100% = 38.4 g
M(CH3COOH) = 60 g/mol
n(CH3COOH) = m/M = 38.4 / 60 = 0.64 mol
M(CH3OH) = 32 g/mol
n(CH3OH) = m/M = 32 / 32 = 1 mol
n(CH3COOH) < n(CH3OH)
CH3COOH+CH3OH-->CH3COOCH3+H2O
n(CH3COOH) = n(CH3COOCH3) = 0.64 mol
M(CH3COOCH3) = 74 g/mol
m(CH3COOCH3) = n*M = 0.64*74 = 47.36 g
ответ 47.36 г
