\(a,n_{NaOH}=1,5.0,2=0,3\left(mol\right)\\ n_{H_2}=\dfrac{5,6}{22,4}=0,25\left(mol\right)\)
PTHH:
CH3COOH + NaOH ---> CH3COONa + H2O
0,3<-----------0,3
2CH3COOH + 2Na ---> 2CH3COONa + H2
0,3----------------------------------------------->0,15
2C2H5OH + 2Na ---> 2C2H5ONa + H2
0,2<---------------------------------------0,1
=> m = 0,2.46 +0,3.60 = 27,2 (g)
b) \(\left\{{}\begin{matrix}\%m_{CH_3COOH}=\dfrac{0,3.60}{27,2}.100\%=66,18\%\\\%m_{C_2H_5OH}=100\%-66,18\%=33,82\%\end{matrix}\right.\)
