CH3COOH +C3H7OH-->

-->CH3COOC3H7

n(CH3COOH) =12/60=0.2моль

n(C3H7OH)=15/60=0.25моль

n(CH3COOC3H7)=0.2моль(по уравнению реакции)

m(CH3COOC3H7)=Mr*n=102*0.2=20.4г

C3H7Cl+NaOH-->C3H7OH+NaCl

m(NaOH)=m(р-ра)*w/100%=20%*25/100%=5г

n(NaOH)=5/40=0.125моль

n(C3H7Cl)=11.78/78.5=0.15

n(C3H7OH)=0.125моль

m(C3H7OH)=0.125*60=7.5г
