You want to prepare an aqueous solution of ethylene glycol, HOCH2CH2OH, in which the mole fraction of solute is 0.125. What mass of ethylene glycol, in grams, should you combine with 955 g of water? What is the mole fraction, molality and mass %?

This seems an awful like a solubility question, before we go on it would be alot easier to refer to water in liters. Another thing that would be helpful is the ksp value for the saturated solution. First write out the formula and since we know that mol ratio is 1/8. from this just write out a chart with all the information u have figure out the molar masses and u sshold start to see your way around this problem. p.s sorry for not doing any of the actual math i dont have a calculator or a periodic table handy.

Gee...I Don't remember my high school chemistry...that was a l-o-o-n- time ago!
