A 8.00L tank at 7.1°C is filled with 4.84g of boron trifluoride gas and 8.04g 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 in the tank. Round each of your answers to 3 significant digits.
boron trifluoride mole fraction: partial pressure:atm
sulfur hexafluoride mole fraction: partial pressure:atm
