CH3CHO + [O] = CH3COOH
1. n(CH3CHO) = m/M = 25/44 = 0.57 моль
2. n(CH3COOH) = n(CH3CHO) = 0.57 моль
3. m (CH3COOH)теор = n*M = 0.57*60 = 34.2 г
4. m (CH3COOH)практ =m (CH3COOH)теор*80%/100% = 34,2*80%/100% = 27,36 г
Ch3COOH + NaOH = CH3COONa + H2O
5. n(NaOH) = n(CH3COOH) = m/M = 27.36/60 = 0.456 моль
6. m (NaOH) = n*M = 0.456*40 = 18.24 г
7. m(NaOH)р-р = m (NaOH)*100%/10% = 182,4 г
