The partial pressures of the gases in a mixture are 0.00461 atm O2, 1.78 atm N2, and 0.975 atm Ar. What is the total pressure of the mixture?

The total pressure of the mixture is 2.76 atm

Explanation:

According to Dalton's law, the total pressure is the sum of individual pressures.

Given : =total pressure of gases = ?

= partial pressure of oxygen = 0.00461 atm

= partial pressure of nitrogen = 1.78 atm

= partial pressure of argon = 0.975 atm

putting in the values we get:

Thus the total pressure of the mixture is 2.76 atm
