\(CH2=CHCOOC_2H_5+KOH\rightarrow Muối+C_2H_5OH\)
0,15 0,15
\(n_{KOH\left(p/ứ\right)}=0,15\left(mol\right)\)
\(m_{KOH}=0,15.56=8,4\left(g\right)\)
Lượng KOH thực tế lấy:
\(8,4.105\%=8,82\left(g\right)\)
\(m_{ethyl}=0,15.100=15\left(g\right)\)
\(m_{C_2H_5OH}=0,15.46=6,9\left(g\right)\)
\(m_{khan}=8,82+15-6,9=16,92\left(g\right)\)
