Fórmula

## Ideal Gas Law The ideal gas law relates the pressure, volume, temperature, and amount of a gas. ### Formula **PV = nRT** where R = 0.082057 L·atm/(mol·K) or 8.314 J/(mol·K). This law is accurate for gases at moderate pressures and temperatures.

Ejemplo Resuelto

1 mole of gas at 273.15 K (0°C) in 22.414 L (STP conditions).

  1. 01P = nRT / V
  2. 02P = 1 * 0.082057 * 273.15 / 22.414
  3. 03P = 22.414 / 22.414
  4. 04P = 1.000 atm (as expected at STP)
