m(ppa CHOOH)=90 g
W(CHOOH)=20%
m(ppaC2H5OH)=40 g
W(C2H5OH)=40%
----------------------
m(CHOOC2H5)-?
m(CHOOH)= 90*20%/100% = 18 g
M(CHOOH)=46 g/mol
n(CHOOH) = m/M=18/46=0.39 mol
m(C2H5OH)=40*40%/100% = 16 g
M(C2H5OH)=46 g/mol
n(C2H5OH)=m/M=16/46=0.35 mol
n(CHOOH)>n(C2H5OH)
CHOOH+C2H5OH-->CHOOC2H5+H2O M(CHOOC2H5)=74 g/mol
n(C2H5OH)=n(CHOOC2H5)= 0.35 mol
m(CHOOC2H5)= n*M = 0.35*74=25.9 g
ответ 25.9 г
