Canvas Classes · Accepted Answer

Strategy:
 A  (v/v) solution contains  of solute in every  of solution. Calculate the mass of the solute and the mass of the solvent () using their respective densities to find molality ().

Step 1: Components in 100 mL solution
- Volume solute ()  Mass .
- Volume solvent ()  Mass .

Step 2: Calculate molality
Moles of .
Mass of solvent .
