Calculate pressure, volume, moles, or temperature using the ideal gas law equation.

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)
