n(CH_3COOH)_0 \cdot (V_{opl})^{-1}=\frac{\frac{m(CH_3COOH)_0}{M(CH_3COOH)}}{5mL} \cdot (V_{opl})^{-1}=\frac{\frac{50mL \cdot 1,049 \frac{g}{mL}}{60,05}}{5mL} \cdot (V_{opl})^{-1}=0,043 mol \cdot (V_{opl})^{-1}

n(C_2H_5OH)_0 \cdot (V_{opl})^{-1}=\frac{\frac{50mL \cdot 0,789 \frac{g}{mL}}{46,07}}{5mL} \cdot (V_{opl})^{-1}=0,0425 mol \cdot (V_{opl})^{-1}

Y=K=\frac{[C_2H_5OOC_2H_5][H_2O]}{[CH_3COOH][C_2H_5OH]}=\frac{(0,2867 \frac{mol}{V})^2}{0,01433 \frac{mol}{V} \cdot 0,01383 \frac{mol}{V}}=4,15

\frac{4,15-4,00}{4,00}=3,75%

CH_3COOH (l) + C_2H_5OH(l) \leftrightarrow C_2H_3OOC_2H_5(l) + H_2O(et)
