19. (Ch5) In a mixture of N_(2)(g) and O_(2)(g) the partial pressure of N_(2)(g) is 0.815 atm . If the total pressure of the mixture is 1.085 atm, the mole fraction of N_(2) in the mixture is a. 0.249 b. 0.27 o c. 0.712 d. 0.815 e. 0.751

Question

Answer 1

To find the mole fraction of

in the mixture, we can use the partial pressure of

and the total pressure of the mixture.The mole fraction (

) is given by the ratio of the partial pressure of

to the total pressure:

Given:- Partial pressure of

(

) = 0.815 atm- Total pressure of the mixture (

) = 1.085 atmSubstituting the values:

Therefore, the mole fraction of

in the mixture is approximately 0.751.So, the correct answer is:e. 0.751
