Homework Statement
What volume (L) of the solvent acetone should be added to 1790 g of the solute methylene chloride to make a solution that is 20.3 g methylene chloride per 100. g solution?
Molar Mass (g/mol)
CH2Cl2 84.93
(CH3)2CO 58.05
Density (g/mL):
CH2Cl2 1.327
(CH3)2CO 0.7899
Name/Formula:
methylene chloride
CH2Cl2
acetone
(CH3)2CO
Homework Equations
percent by mass = mass of solute/ mass of solution x 100
The Attempt at a Solution
Im taking organic chem right now and this is a question for one of my chem lab homeworks so I am a little rusty with these kinds of problems...but this is where I am at/stuck
Looking for (L) of (CH3)2CO Given: 1790g CH2Cl2 and the mass percent fraction is:
20.3g CH2Cl2/100g soln.
I know that you have to use the densities to convert from g-->L but I just don't know how to get to that point..
