Answer to Question #107710 in General Chemistry for scarlett

Question

The total barometric pressure in the room is 0.98atm. If all of the gases, other than nitrogen
gas, has a pressure of 0.72atm, what is the partial pressure of nitrogen gas in the room?

Answer 1

Let the gas mixture be ideal.

Then Dalton’s law: the total pressure of a mixture of ideal gases is equal to the sum of the partial pressures of each gas in the mixture.

According this law, the partial pressure of gaseous nitrogen in the room wiil be:

0,98 - 0.72 = 0,26 atm.
