Ideal Gas Law ( Use the GRESA method )

1. 6.5 moles of carbon dioxide gas are present in a container with a volume of 31.5 L. What is the pressure of this gas (in atm) if the temperature is 65'C?

2. How much space will 5.0 moles of sulfur hexafluoride occupy if the temperature and pressure of the gas are 125°C and 8.5 atm respectively?

3. What is the mass of 6.2 L of nitrogen gas at 250C and 12.0 atm? ( molar mass of nitrogen= 14 g/mol)
