I am stuck on this last question can someone help me ? A gas has a pressure of 50.0 mm Hg at 247°C. What will be the final temperature, in K, if the pressure changes to 2.53 kPa and the volume does not change?
I have been trying to use the formula (V1)P1) / (n1)(T1) = (V2)P2) / (n2)(T2) but can not get to the answer.
