an agueous solution of ethlylene glycol (C2H6O2) is 40% ethylene glycol by mass, and has a density of 1.05g/ml. What are the molarity, molality, and mole fraction of the solution?

Question

Do you know how to solve this...I am kinda lost..please help

Answer 1

Assume 1kg of the stuff. Now you have 400 g ethylene, and 600g water. The volume you have is .6/1.05 liters.

YOu have everything you now need to solve (you do have to figure mole mass from the formula)>
