Questions & Step-by-Step Solutions
For an ideal solution, if the mole fraction of the solvent is 0.75, what is the vapor pressure of the solution if the vapor pressure of the pure solvent is 100 mmHg?
Step 1: Understand that we are using Raoult's Law, which states that the vapor pressure of a solution is equal to the mole fraction of the solvent multiplied by the vapor pressure of the pure solvent.
Step 2: Identify the mole fraction of the solvent, which is given as 0.75.
Step 3: Identify the vapor pressure of the pure solvent, which is given as 100 mmHg.
Step 4: Multiply the mole fraction of the solvent (0.75) by the vapor pressure of the pure solvent (100 mmHg).
Step 6: Conclude that the vapor pressure of the solution is 75 mmHg.
Raoult's Law – Raoult's Law states that the vapor pressure of a solvent in a solution is equal to the vapor pressure of the pure solvent multiplied by the mole fraction of the solvent in the solution.
