Expert Answer

Step 1

Molality of a non-volatile, non-electrolyte solute that is needed to raise the boiling point of water by 7.10°C (Kb = 0.520°C/m) is to be calculated.

Step 2

The properties that depend only on the concentration of the solute are known as Colligative properties. Such colligative properties are vapor pressure lowering, boiling point elevation, freezing point depression and osmotic pressure.

The given question is related to boiling point elevation.

When a non-volatile solute is added to solution, its vapor pressure is lowered which leads to the increase in its boiling point. This elevation in boiling point is directly proportional to the molal concentration of solute.
