Question

2. Define and explain Raoult's law. How is it
useful in determining the molecular weight
of a non - volatile solute ?
3. Define Raoult's law for lowering of vapour
pressure. How is the law useful in determining
the molecular weight of a solvent when a
known non
volatile solute is dissolved ?
4. Define Solubility. Discuss the factors affect-
