Homework Help: Chemistry

Posted by Luc on Monday, March 1, 2010 at 3:13am.

A 1.33 m solution of the solute diethyl ether dissolved in the solvent tetrahydrofuran is available. Calculate the mass(kg) of the solution that must be taken to obtain 0.4716 kg of diethyl ether.

Name/Formula:
diethyl ether = (C2H5)2O
tetrahydrofuran = C4H8O

Molar Mass(g/mol):
(C2H5)2O = 74.12
C4H8O = 72.12

Density(g/mL):
(C2H5)2O = 0.7138
C4H8O = 0.8892

Answer = 5.256 kg

This question is about molality. I've tried several ways of solving this type of problem, but I never seem to come up with the correct answer. Can someone give me a step by step explanation on how to come to the answer written above?
