Strategy:
 To calculate molality (), we need the mass of the solvent. By considering 1 liter of the 0.8 M solution, we can find the total mass of the solution and the mass of the , allowing us to find the mass of the water (solvent).

Step 1: Consider 1 Liter (1000 mL) of the solution
- Total Mass: Volume  Density = 
- Mass of Solute: Moles  Molar mass =

Step 2: Calculate the mass of the solvent (water)

Step 3: Calculate Molality ()

Step 4: Express as 
.
