Answer:
45.3 KPa
Explanation:
From the question given above, the following data were obtained:
Total pressure (Pâ‚ś) = 101.3 KPa
Pressure of Hydrogen (Pâ‚•) = 56 KPa
Pressure of Oxygen (Pâ‚’) =?
The pressure of oxygen in the mixture can be obtained as follow:
Pâ‚ś = Pâ‚• + Pâ‚’
101.3 = 56 + Pâ‚’
Collect like terms
101.3 – 56 = Pₒ
Pâ‚’ = 45.3 KPa
Thus, the pressure of oxygen in the mixture is 45.3 KPa
