A 9.00 L tank at 26.5 C is filled with 15.2 g of boron trifluoride gas and 12.7 g of sulfur hexafluoride gas. You can assume both gases behave as ideal gases under these conditions. Calculate the mole fraction and partial pressure of each gas, and the total pressure in the tank. a) Boron trifluoride - mole ratio - partial pressure b) Sulfur hexafluoride -mole ratio -partial pressure
