Ideal Gas Law
PV = nRT
R = 0.0821 L·atm/(mol·K)
Understanding the Ideal Gas Law
The Ideal Gas Law describes the relationship between pressure, volume, temperature, and amount of gas. It combines Boyle's Law, Charles's Law, and Avogadro's Law into a single equation that works well for most gases at moderate temperatures and pressures.
Formula
PV = nRT
Pressure × Volume = Moles × Gas Constant × Temperature
R = 0.0821 L·atm/(mol·K)
