In a mixture of 0114 and N2 gases, the mol fraction of C114 is found to be 0.600. The total pressure of the mixture is 1.60 atm. What is the partial pressure of N2 in the mixture?
A 0.640 B 0.96 C 0.32
D 0.48 E 0.20

The partial pressure of N₂ : A. 0.64 atm

Dalton's law of partial pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases  

Can be formulated:  

P tot = P1 + P2 + P3 ....  

The partial pressure is the pressure of each gas in a mixture  

For partial gas :

Pgas₁=x₁.P tot

x₁ = mole fraction of gas 1

mol fraction CH₄=0.6

P tot = 1.6 atm

mol fraction N₂ :

The partial pressure of N₂ :
