A mixture of He, N2, and Ar has a pressure of 24.5 atm at 28.0 °C. If the partial pressure of He is 2671 torr and that of Ar is 3345 mm Hg, what is the partial pressure of N2?

Answer #1

partial pressure of He = 2671 torr = 3.52 atm

partial presuure of ARGON = 3345mm of Hg = 4.40 atm

according to dalton law of partial pressure

total pressure = sum of partiaal pressures of helium,argon and nitrogen

                        24.5 atm = 3.52+4.40 +partial pressure of nitrogen

                           partial pressure of nitogen = 16.58 atm
