Raoult S Law And Colligative Properties

Step 1: According to Raoult’s Law, the vapour pressure of a solution is given by: Where: - is the vapour pressure of the solution. - is the vapour pressure of the pure solvent. - and are the mole fractions of the solvent and solute, respectively. Step 2: The equation can be rewritten as: Since the solute has no vapour pressure, we can ignore the second term. Step 3: Rearranging the equation to solve for the mole fraction of the solute : Step 4: Substitute the given values: Thus, the mole fraction of the solute is:
