A mixture of Oxygen and Hydrogen occupies a pressure of 101.3kPa. The pressure of Hydrogen is 56kpa. Calculate the pressure of oxygen.

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

false

because it does not have the potential to be entirely used up

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
