We’re being asked to calculate for the molality of 32.0 % by weight aqueous solution of acetone (C3H6O). 

When calculating for molality, we use the following equation:

Aqueous solution → water is the solvent

                                   Solute → acetone


We will calculate the molality of the solution using the following steps:

Step 1. Determine the composition of the solution.
Step 2. Calculate the moles of the solute.
Step 3. Calculate the mass of the solvent (in kg).
Step 4. Calculate the molality of the solution.


Step 1. Determine the composition of the solution.
