Question: If the vapor pressure of pure solvent A is 100 mmHg, and the mole fraction of A in the solution is 0.6, what is the vapor pressure of the solution according to Raoult\'s Law?

Options:

1. 60 mmHg
2. 100 mmHg
3. 40 mmHg
4. 80 mmHg

Correct Answer: 60 mmHg

Solution:

Using Raoult\'s Law, P_solution = X_A * P_A^0 = 0.6 * 100 mmHg = 60 mmHg.
