Question: In a binary solution of A and B, if the vapor pressure of A is 80 mmHg and that of B is 40 mmHg, what is the total vapor pressure when both are present?

Options:

40 mmHg
80 mmHg
120 mmHg
100 mmHg

Correct Answer: 100 mmHg

Solution:

The total vapor pressure is the sum of the partial pressures: P_total = P_A + P_B = 80 mmHg + 40 mmHg = 120 mmHg.

Questions & Step-by-Step Solutions

In a binary solution of A and B, if the vapor pressure of A is 80 mmHg and that of B is 40 mmHg, what is the total vapor pressure when both are present?

Step 1: Identify the vapor pressure of component A, which is given as 80 mmHg.
Step 2: Identify the vapor pressure of component B, which is given as 40 mmHg.
Step 3: To find the total vapor pressure, add the vapor pressures of A and B together.
Step 4: Calculate the total vapor pressure: 80 mmHg (from A) + 40 mmHg (from B) = 120 mmHg.

Raoult's Law – The total vapor pressure of a solution is the sum of the partial pressures of each component, which can be calculated using Raoult's Law.
