1) СН3-СН2-СООН + НО-С2Н5 = СН3-СН2-СО-О-С2Н5 +Н2О
m(CH3-CH2-COOH)= m x w=444 x 0.1= 44.4 г
n(CH3-CH2-COOH)= 44.4/84=0.53 моль
n(CH3-CH2COOH)= n(C2H5OH)
m(C2H5OH)= nxM=0.53 x 46= 24.3 г
2) CH3COOH +NaOH= CH3COONa +H2O
m (CH3COOH)= mxw= 120 x 0.1= 12 г
n(CH3COOH) 12/60= 0.2 моль
n(CH3COOH)= n(NaOH)
m(NaOH)= 0.2 x 40= 8 г
8 х100/15=53.3 г
