• volume
• moles
• gas law constant
• temperature

 A 2.75 L sample of gas is at a pressure of 1.95 atm and 22.0 °C. What volume does the same sample of gas occupy when the pressure is decreased to 0.599 atm and the temperature increases to 45°C? (Type in numbers only, no units, check sig figs & round appropriately)

Determine the temperature in celsius for 0.0470 mol of gas to fill a balloon to 1.20 L under 0.998 atm pressure.
