Question

A 9.00 L tank at 20.7 °C is filled with 2.02 g of dinitrogen difluoride gas and 8.41 g of chlorine pentafluoride 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. Be sure your answers have the correct number of significant digits. dinitrogen difluoride partial pressure chlorine pentafluoride partial pressure Total pressure in tank:
