Sagot :
Partial pressure of helium gas in the tank is 162.24 atm.
Partial Pressure:
A partial pressure is the imaginary pressure that a gas would have if it were to occupy the complete volume of the initial mixture by itself at the same temperature. Each gas in a mixture of gases has a partial pressure.
Explanation:
Total pressure in Heloix (P) = 208 atm
The mole fraction of an individual gas component in an ideal gas mixture can be expressed in terms of the component's partial pressure or the moles of the component
Mole fraction of oxygen (X₀) = 0.220
The sum of the mole fractions of all the components present must equal 1.
Mole fraction of helium (Xₐ) = 1-(X₀) = 1- 0.220= 0.78
According to Dalton's law of partial pressure.
Partial pressure of an individual gas component in an ideal gas can be obtained using this expression:
Partial pressure of oxygen gas in Heloix: P*X₀ = 208 * 0.22 = 45.76 atm
Partial pressure of helium gas in Heloix: P*Xₐ = 208 * 0.78 = 162.24 atm
Partial pressure of helium gas is 162.24 atm.
