Answer to Question #153953 in General Chemistry for Phyroe

Question

Calculate the mole fraction of solute in a solution maintaining 75 g of ethanol( C2H6O) in 450 g of water.

Answer 1

Calculate moles of ethanol: 75 grams x 1 mol / 46 grams = 1.6304 moles

Calculate moles of water: 450 grams x 1 mol / 18 grams = 25 moles

Mole fraction = moles of component / total moles in solution = 1.6304 / (1.6304 + 25) = 0.0612
