Question

A tank of gas has partial pressures of nitrogen and oxygen equal to 1.61 × 104 kPa and 4.34 × 103 kPa , respectively.What is the total pressure of the tank?

Answer 1

`20.44* 10^3 kPa` is the total pressure of the tank.

Step-by-step explanation:

Partial pressures of nitrogen =
`p_(N_2)=1.61* 10^4 kPa`

Partial pressure of oxygen =
`p_(O_2)=4.34* 10^3 kPa`

Total pressure of gases in the tank = P

Applying Dalton's law of partial pressures :

`P=p_(N_2)+p_(O_2)=1.61* 10^4 kPa+4.34* 10^3 kPa`

`P=20.44* 10^3 kPa`

`20.44* 10^3 kPa` is the total pressure of the tank.
