Homework Help: Chemistry

Posted by Luc on Tuesday, March 2, 2010 at 2:22am.

Calculate the molality (m) of a 6.56 kg sample of a solution of the solute acetone dissolved in the solvent ethanol if the sample contains 1.44 kg of acetone.

Additional info:

Molar Mass (g/mol)
acetone = 58.05
ethanol = 46.07

Density (g/mL)
acetone = 0.7899
ethanol = 0.7893

Dr. Bob, I asked a question like this about molality and the step by step explanation that you provided helped greatly. Could you please help me out with this one. It is slightly different and I'm really confused. Thank you!
