A 9.00L tank at 13.6°C is filled with 11.8g of dinitrogen monoxide gas and 2.27g of chlorine pentafluoride gas. You can assume both gases behave as ideal gases under these conditions.

Calculate the mole fraction of each gas. Round each of your answers to 3 significant digits.

1) Gas: Dinitrogen monoxide 

Mole Fraction: ?

2) Gas: Chlorine pentafluoride

Mole Fraction: ? 

A 9.00 L tank at 8.56 °C is filled with 693 g of carbon monoxide gas and 14.3 g of boron trifuoride 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. mole fraction: carbon monoxide partial pressure: mole fraction: boron trifluoride partial pressure Total pressure in tank:
