The calculation depends on whether you wish to calculate the pressure using an ideal model or a real life model. For simplicity, we will assume ideal conditions.

The ideal gas equation is as follows:

#PV=nRT#

Where:

#P# = pressure
#V# = volume
#n# = moles
#R# = constant
#T# = temperature in kelvin

To calculate pressure, simply rearrange the formula algebraically and use the appropriate values:

#P = (nRT)/V#
