What is the ideal gas law?

The ideal gas law relates pressure (P), volume (V), amount (n), and temperature (T) of an ideal gas: PV = nRT, where R is the universal gas constant (0.08206 L*atm/(mol*K)).

What units should I use?

Use atmospheres (atm) for pressure, liters (L) for volume, moles (mol) for amount, and Kelvin (K) for temperature when using R = 0.08206.

Standard Temperature and Pressure (STP) is defined as 273.15 K (0 degrees C) and 1 atm. At STP, one mole of an ideal gas occupies 22.4 liters.

When does the ideal gas law break down?

The ideal gas law is less accurate at very high pressures, very low temperatures, or for gases with strong intermolecular forces. Real gas behavior requires equations like van der Waals.
