The Ideal Gas Law (PV = nRT)

The Ideal Gas Law is the equation of state of a hypothetical ideal gas. It is a good approximation of the behavior of many gases under various conditions, although it has several limitations.

P: Pressure (atm)
V: Volume (Liters)
n: Number of moles
R: Ideal Gas Constant (0.08206 L·atm/mol·K)
T: Absolute Temperature (Kelvin)

Note: Temperature must be in Kelvin (K = °C + 273.15).
