\(n_{CH_3COOH}=\dfrac{150.20\%}{60}=0,5\left(mol\right)\)
PTHH: K2CO3 + 2CH3COOH --> 2CH3COOK + CO2 + H2O
0,25<-----0,5
=> mK2CO3 = 0,25.138 = 34,5 (g)
\(m_{ct}=\dfrac{20.150}{100}=30\left(g\right)\)
\(n_{CH3COOH}=\dfrac{30}{60}=0,5\left(mol\right)\)
Pt : \(2CH_3COOH+K_2CO_3\rightarrow2CH_3COOK+CO_2+H_2O|\)
2 1 2 1 1
0,5 0,25
\(n_{K2CO3}=\dfrac{0,5.1}{2}=0,25\left(mol\right)\)
⇒ \(m_{K2CO3}=0,25.138=34,5\left(g\right)\)
