Answer:

98.4 kPa

Explanation:

Step 1: Given and required data

  • Partial pressure of water vapor at 60°C (pH₂O): 19.9 kPa (this info is tabulated)
  • Partial pressure of nitrogen (pN₂): 53.0 kPa
  • Partial pressure of helium (pHe): 25.5 kPa

Step 2: Calculate the total pressure of the gaseous mixture

The total pressure of the gaseous mixture (P) os equal to the sum of the partial pressures of the gases that form it.

P = pH₂O + pN₂ + pHe

P = 19.9 kPa + 53.0 kPa + 25.5 kPa = 98.4 kPa

The total pressure of the wet gas mixture is 98.4 KPa

Dalton's law of partial pressure

This law states that at constant temperature, the total pressure of a mixture of gases is equal to the sum of the partial pressure exerted by each gas. Mathematically, it is expressed as

Total pressure = partial pressure of A + partial pressure of B

How to determine the total pressure

  • Partial pressure of water vapor at 60°C (pH₂O) =  19.9 KPa
  • Partial pressure of nitrogen (pN₂) =  53.0 KPa
  • Partial pressure of helium (pHe) = 25.5 KPa
  • Total pressure (P) =?

P = pH₂O + pN₂ + pHe

P = 19.9 + 53 + 25.5

P = 98.4 KPa
