56 g of nitrogen and 96 g of oxygen are mixed isothermally and at a total pressure of 10 atm. The partial pressures of oxygen and nitrogen (in atm) are respectively.

Question

56 g of nitrogen and 96 g of oxygen are mixed isothermally and at a total pressure of 10 atm. The partial pressures of oxygen and nitrogen (in atm) are respectively., 5, 5, 2, 8, 6, 4, 8, 2

MARKS App · Accepted Answer

According to Dalton’s law, Partial pressure of a component = Mole fraction × Total pressure As mass of N 2 = 56 g Mass of O 2 = 96 g Total pressure = 10 atm n N 2 = 56 28 = 2 , n O 2 = 96 32 = 3 x N 2 = 2 2 + 3 = 0.4 x O 2 = 3 2 + 3 = 0.6 p N 2 = 0.4 × 10 = 4 a t m p O 2 = 0.6 × 10 = 6 a t m
