Number of moles of dioxygen = 70.6g = 2.21 mol
Number of moles of neon = 167.5g = 8.375 mol
Mole fraction of dioxygen = 2.21 = 0.21
Mole fraction of neon = 1 0.21 = 0.79
Partial pressure of gas = Mole fraction × Total pressure
Partial pressure of O2 = 0.21 × 25 bar = 5.25 bar
Partial pressure of Ne = 0.79 × 25 bar = 19.75 bar
