Question

Sapling Learning Map The essential oil found in cloves, eugenol, can be isolated by steam distillation because it is insoluble in water and has a measurable vapor pressure at 100 even though it has a much higher boiling point than water Use data from the table to calculate the volume of eugenol in 30 mL of distillate. Volume of eugenol present in distillate watereugenol Molar18 g/mol 164 g/mol mass Number mL Boiling 1100 1254 point Vapor760 mmHg 4.0 mmHg pressure at100 Density 1.0 gm 1.05 g/mL HO eugenol

Explanation / Answer

Solution:-

Molar Mass of Water: 18 g/mol
Molar Mass of Eugenol: 164 g/mol
Boiling point of water: 100 degrees C
Boiling point of eugenol: 254 degrees C
Vapor pressure of Water at 100 degrees C: 760 mmHG
Vapor pressure of Eugenol at 100 degrees C: 4.0 mmHG


HINT: Steam distillation is particularly useful for purifying materials that decompose before reaching their normal boiling point. Steam causes high-boiling components that are immiscible in water to boil at significantly lower temperatures than their normal boiling point. Because the mole fraction of the components only depends on the vapor pressure of the components:

I have attempted this problem numerous times here is what i am doing what am i doing wrong?

Xorg = 4.0/4.0+760 = 0.0053
1-0.0053=0.9947 = XH20

mH2O = 0.9947 * 18 = 17.9046
morg = 0.0053 * 164 = 0.8692

m%org = [0.8692/ (0.8692 + 17.9046)] * 100 = 4.62%
Rounded to 5%
