A mixture of He, NE, and N2 gases has a pressure of 1.043 atm. If the pressures of He and Ne are 0.137 atm and 0.566 atm, respectively, what is the partial pressure of N2 in the mixture?

Answer : The partial pressure of nitrogen gas in the mixture is, 0.34 atm

Explanation :

According to the Dalton's Law, the total pressure of the gas is equal to the sum of the partial pressure of individual gases.

Formula used :

where,

= total pressure of gas  = 1.043 atm

= partial pressure of helium gas  = 0.137 atm

= partial pressure of neon gas  = 0.566 atm

= partial pressure of nitrogen gas  = ?

Now put all the given values in the above formula, we get:

Thus, the partial pressure of nitrogen gas in the mixture is, 0.34 atm
