Ideal gas law
We have ideal conditions or assumptions regarding gases using the Kinetic Molecular Theory (KMT).
We also have an Ideal Gas Law to calculate multiple pieces of information at the same time.
PV = nRT

Ideal gas law
PV = nRT
P = pressure (atm) n = moles of gas (moles)
V = volume (L) T = temperature (K)
R = (l*atm)/(k*mol)
