Problem: Determine the partial pressure of each gas as shown in the figure below. Note: The relative numbers of each type of gas are depicted in the figure.

FREE Expert Solution

Recall that the partial pressure of a gas (PGas) in a mixture is given by:


Pgas=χgasPtotal


Mole fraction:


χgas=moles gastotal moles


Solving for partial pressure of each gas:

  • # of particles = # of moles of each gas


PHe=χHePtotalPHe=(510)(1.00 atm)


PHe0.50 atm
