A 10.0L tank at 7.39°C is filled with 2.66g of dinitrogen monoxide gas and 19.6g of sulfur tetrafluoride gas. You can assume both gases behave as ideal gases under these conditions.

Calculate the total pressure in the tank. Round your answer to 3 significant digits.

A 9.00 L tank at 16.4°C is filled with 15.8 g of dinitrogen difluoride gas and 2.60 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. Round each of your answers to 3 significant digits.

A 10.00L tank at −1.1°C is filled with 18.6g of chlorine pentafluoride gas and 14.6g of carbon monoxide 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.
