A vessel under 2.015 atm pressure containing nitrogen and water vapor has a total pressure of 2.015 atm. The partial pressure of N₂ is 1.908 atm. Calculate the partial pressure of the water vapor. A) 0.107 atm B) 1.908 atm C) 2.015 atm D) 3.923 atm

Question

Quizplus · Accepted Answer

According to Dalton's law of partial pressures, the total pressure of a mixture of gases is equal to the sum of the partial pressures of the individual gases. Therefore, the partial pressure of water vapor can be calculated as follows:

Partial Pressure of Water Vapor = Total Pressure - Partial Pressure of Nitrogen

Partial Pressure of Water Vapor = 2.015 atm - 1.908 atm

Partial Pressure of Water Vapor = 0.107 atm

Therefore, the correct choice is A) 0.107 atm.
