1. The problem statement, all variables and given/known data 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 2. Relevant equations percent by mass = mass of solute/ mass of solution x 100 3. 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 im 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..
