Using the ideal gas equation, we can solve this problem. The equation is a combination of the three gas laws: Boyle's law, Charles's law and Avogadro's law.
It is mathematically expressed as;
PV = nRT
where P is the pressure
V is the volume
R is the gas constant
T is the temperature
n is the number of moles
All the parameters are in the appropriate units and we simply solve for the volume of the gas;
