Answer :
Final answer:
The total pressure for a mixture of gases is calculated by summing the partial pressures of each gas component. In this case, the total pressure is a. 2.37 kPa.
Explanation:
The total pressure for a mixture of gases is calculated by summing the partial pressures of each gas component. According to Dalton's law of partial pressures, the total pressure of a mixture of ideal gases is equal to the sum of the partial pressures of the component gases.
In this case, the total pressure is obtained by adding the partial pressures of the four gases: 0.39 kPa + 0.53 kPa + 0.73 kPa + 0.72 kPa = 2.37 kPa.
Therefore, the correct answer is a. 2.37 kPa.
