Given information:
- The sample of air contains only N2, O2, and H2O.
- The air is saturated with water vapors.
- The total pressure of the sample is 640 torr.
- The vapor pressure of water is 40 torr.
- The molar ratio of N2 to O2 is 3:1.
To find:
The partial pressure of N2 in the sample.
Solution:
Step 1: Calculate the partial pressure of water vapor:
Since the air is saturated with water vapor, the partial pressure of water vapor is equal to its vapor pressure, which is given as 40 torr.
Step 2: Calculate the partial pressure of N2:
Let's assume the number of moles of N2 in the sample is 3x, where x is a constant.
Since the molar ratio of N2 to O2 is 3:1, the number of moles of O2 in the sample would be x.
Therefore, the total number of moles of N2 and O2 in the sample is 3x + x = 4x.
The total pressure of the sample is the sum of the partial pressures of N2, O2, and water vapor:
Total pressure = partial pressure of N2 + partial pressure of O2 + partial pressure of water vapor
640 torr = partial pressure of N2 + partial pressure of O2 + 40 torr
The partial pressure of O2 can be calculated using the molar ratio:
Partial pressure of O2 = (1/4) * (640 torr - 40 torr) = 150 torr
Therefore, the partial pressure of N2 can be calculated as:
Partial pressure of N2 = 640 torr - 150 torr - 40 torr = 450 torr.
Answer:
The partial pressure of N2 in the sample is 4.450 torr.
- The sample of air contains only N2, O2, and H2O.
- The air is saturated with water vapors.
- The total pressure of the sample is 640 torr.
- The vapor pressure of water is 40 torr.
- The molar ratio of N2 to O2 is 3:1.
To find:
The partial pressure of N2 in the sample.
Solution:
Step 1: Calculate the partial pressure of water vapor:
Since the air is saturated with water vapor, the partial pressure of water vapor is equal to its vapor pressure, which is given as 40 torr.
Step 2: Calculate the partial pressure of N2:
Let's assume the number of moles of N2 in the sample is 3x, where x is a constant.
Since the molar ratio of N2 to O2 is 3:1, the number of moles of O2 in the sample would be x.
Therefore, the total number of moles of N2 and O2 in the sample is 3x + x = 4x.
The total pressure of the sample is the sum of the partial pressures of N2, O2, and water vapor:
Total pressure = partial pressure of N2 + partial pressure of O2 + partial pressure of water vapor
640 torr = partial pressure of N2 + partial pressure of O2 + 40 torr
The partial pressure of O2 can be calculated using the molar ratio:
Partial pressure of O2 = (1/4) * (640 torr - 40 torr) = 150 torr
Therefore, the partial pressure of N2 can be calculated as:
Partial pressure of N2 = 640 torr - 150 torr - 40 torr = 450 torr.
Answer:
The partial pressure of N2 in the sample is 4.450 torr.
