m(CH3OH) = 16 g
---------------------------
m(CH3COOCH3) = ?
CH3COOH+CH3OH -->CH3COOCH3+H2O
M(CH3OH) = 32 g/mol
n(CH3OH) = m/M = 16 / 32 = 0.5 mol
n(CH3OH) = n(CH3COOCH3) = 0.5 mol
M(CH3COOCH3) = 44 g/mol
m(CH3COOCH3) = n*M = 0.5 * 44 = 22 g
ответ 22 г

С2H6-->C2H4+H2
C2H4+HOH-->C2H5OH
C2H5OH-->CH3COH+H2
CH3COH+Ag2O-->CH3COOH+2Ag
CH3COOH+C2H5OH-->CH3COOC2H5+H2O
