If the mixture of 7 g of N₂ and 8 g of Ar in a cylinder has the total pressure 27 bar . What is the partial pressure of N₂ ? (Atomic mass of N=14 ~g ~mol ⁻¹, Ar =40 ~g ~mol ⁻¹ )

Step-by-step solution

Moles of N₂= 7 28 = 1 4 Moles of Ar = 8 40 = 1 5 Partial pressure =X_ N₂ P_T Partial pressure of aligned N₂ & = 1 4 1 4 + 1 5 27 & = 1 4 9 20 27 & = 1 4 20 9 27 & =15 bar aligned
