How do you calculate pressure of gas in a chamber after it is heated to 819K?

Use the ideal gas law: PV=nRT. For a given amount of gas in a chamber the pressure is directly proportional to the temperature (in Kelvins).

gay-lussac's law:

P1/T1 = P2/T2

gas law

PV = nRT

depending on what info was given to you.
