Ideal Gas Law Calculator — Formula
## 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.

Exemplo Resolvido
1 mole of gas at 273.15 K (0°C) in 22.414 L (STP conditions).
- P = nRT / V
- P = 1 * 0.082057 * 273.15 / 22.414
- P = 22.414 / 22.414
- P = 1.000 atm (as expected at STP)
