CÁLCULOS
a) Calculando los % en peso de cada componente:
ACIDO EN AGUAAl 10 % :
* CH3COOH
1ml de CH3COOH x 1.049gml=1.049g de CH3COOH
* H2O
9 ml De H2O x 0.99829 gml=8.984 g de H2O
* N – butanol
1.3 ml de n-butanol x 0.81gml=1.053 g de n-butanol
W total = W de CH3COOH + W de agua + W del n- butanol
W total = 1.049 + 8.984 + 1.053
W total = 11.086
* CH3COOH
1.049g de CH3COOH11.086 g total x100%=9.46%
* H2O
8.984 g den-butanol 11.086 g totalx100=81.04%
* N – butanol
1.053 g de H2O11.086 g total x 100%=9.50%
Al 15 % :
* CH3COOH
1.5 ml de CH3COOH x 1.049gml=1.5735g de CH3COOH
* H2O
8.5 ml De H2O x 0.99829 gml=8.486 g de H2O
* N – butanol
2.5 ml de n-butanol x 0.81gml=2.025 g de n-butanol
W total = W de CH3COOH + W de agua + W del n- butanol
W total = 1.5735 + 8.486 + 2.025W total = 12.0845

* N – butanol
4.5 ml de n-butanol x0.81gml=3.645 g de n-butanol
W total = W de CH3COOH + W de agua + W del n- butanol
W total = 2.098 + 7.986 + 3.645
W total = 13.729

Al 25 % :
* CH3COOH
2.5 ml de CH3COOH x 1.049gml=2.6225 gde CH3COOH
* H2O
7.5 ml De H2O x 0.99829 gml=7.487 g de H2O
* N – butanol
7.5 ml de n-butanol x 0.81gml=6.075 g de n-butanol
W total = W de CH3COOH + W de agua + W del n- butanol
W total = 2.6225 + 7.487 + 6.075
W total = 16.1845
