Calculate the mole fraction of ethylene glycol (C₂H₆O₂) in a solution that is 85% by mass ethylene glycol in water.

Question

Quizplus · Accepted Answer

The mole fraction of ethylene glycol is 0.62. This can be calculated using the formula:Mole fraction of ethylene glycol = Mass of ethylene glycol / (Mass of ethylene glycol + Mass of water)Mass of ethylene glycol = 85% * 100 g = 85 gMass of water = 100 g - 85 g = 15 gMole fraction of ethylene glycol = 85 g / (85 g + 15 g) = 0.62
