A container filled with a mixture of fluorine gas and neon gas exerts a total pressure of 8.20 atm. There are 50.0 g of fluorine gas (F₂) in the container which exerts a pressure of 5.00 atm. 1.32 moles of fluorine gas (F₂) exert a pressure of 5.00 atm. The total pressure of the mixture is 8.20 atm. What percentage of the pressure is due to the fluorine gas?
