You have a sample of gas in a flask with a volume of 250 mL. At 25.5 degrees Celcius, the pressure of the gas is 300 mm Hg. If you decrease the temperture to -5.0 degrees celcius, what is the gas pressure at this lower temperture?
P1/T1 = P2/T2.
Don't forget to change celsius to Kelvin. Note the correct spelling of Celsius.
