A 5.00L tank at 28.4°C is filled with 6.03g of sulfur hexafluoride gas and 8.62g of chlorine pentafluoride gas. You can assume both gases behave as ideal gases under these conditions.

Calculate the partial pressure of each gas, and the total pressure in the tank. Round each of your answers to 3 significant digits.

1) sulfur hexafluoride: partial gas = ?

2) chlorine pentafluoride: partial gas = ? 

3) total pressure in tank = ?

A sample of an unknown compound is vaporized at 120.°C. The gas produced has a volume of 2020.mL at a pressure of 1.00 atm, and it weighs 6.52g.

Assuming the gas behaves as an ideal gas under these conditions, calculate the molar mass of the compound. Round your answer to 3 significant digits.

An arctic weather balloon is filled with 13.8L of helium gas inside a prep shed. The temperature inside the shed is 12.°C. The balloon is then taken outside, where the temperature is −13.°C. Calculate the new volume of the balloon.

You may assume the pressure on the balloon stays constant at exactl 1 atm. Round your answer to 3 significant digits.

A reaction between liquid reactants takes place at 2.0°C in a sealed, evacuated vessel with a measured volume of 35.0L. Measurements show that the reaction produced 33.g of boron trifluoride gas.

Calculate the pressure of boron trifluoride gas in the reaction vessel after the reaction. You may ignore the volume of the liquid reactants. Round your answer to 2 significant digits.
