Answer 1

CH3COOH + C2H5OH --> CH3COOC2H5 + H2O
m(CH3COOH) = 400 * 0.97 * 0.15 = 58.2 грамма
n(ch3cooh) = 58.2/60 = 0.97 моль
n(C2H5OH) = 20/46 моль
Mr(CH3COOC2H5) = 88 г/моль
n(CH3COOC2H5) = n(C2H5OH)
x/88 = 20/46
x = 20 * 88/46 = 38.26 г.

Answer 2

CH3COOH + C2H5OH --> CH3COOC2H5 + H2O
m(CH3COOH) = 400 * 0.97 * 0.15 = 58.2 грамма
n(ch3cooh) = 58.2/60 = 0.97 моль
n(C2H5OH) = 20/46 моль
Mr(CH3COOC2H5) = 88 г/моль
n(CH3COOC2H5) = n(C2H5OH)
x/88 = 20/46
x = 20 * 88/46 = 38.26 г.

Answer 3

CH3COOH + C2H5OH --> CH3COOC2H5 + H2O
m(CH3COOH) = 400 * 0.97 * 0.15 = 58.2 грамма
n(ch3cooh) = 58.2/60 = 0.97 моль
n(C2H5OH) = 20/46 моль
Mr(CH3COOC2H5) = 88 г/моль
n(CH3COOC2H5) = n(C2H5OH)
x/88 = 20/46
x = 20 * 88/46 = 38.26 г.

Answer 4

CH3COOH + C2H5OH --> CH3COOC2H5 + H2O
m(CH3COOH) = 400 * 0.97 * 0.15 = 58.2 грамма
n(ch3cooh) = 58.2/60 = 0.97 моль
n(C2H5OH) = 20/46 моль
Mr(CH3COOC2H5) = 88 г/моль
n(CH3COOC2H5) = n(C2H5OH)
x/88 = 20/46
x = 20 * 88/46 = 38.26 г.

Answer 5

CH3COOH + C2H5OH --> CH3COOC2H5 + H2O
m(CH3COOH) = 400 * 0.97 * 0.15 = 58.2 грамма
n(ch3cooh) = 58.2/60 = 0.97 моль
n(C2H5OH) = 20/46 моль
Mr(CH3COOC2H5) = 88 г/моль
n(CH3COOC2H5) = n(C2H5OH)
x/88 = 20/46
x = 20 * 88/46 = 38.26 г.
