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

<span>Chemical reactivity of all of the different elements in the periodic table depends on the number of electrons in that last, outermost level, called the valence level or valence shell. In the case of gold, there is only </span>one valence electron<span> in its valence level. Hope I helped! :)</span>
