Strategy:
 To convert molarity to molality, follow the relationship . Find the mass of the solvent by subtracting the mass of the solute () from the total mass of 1 Litre of solution (Density ).

Step 1: Find components for 1 L solution
- Moles of .
- Mass of solute .
- Mass of solution .

Step 2: Calculate molality
