Calcolatore Legge Gas Ideali
Calcola pressione, volume, temperatura o moli usando la legge dei gas ideali PV=nRT.
Pressione (P)
1.0000 atm
Pressure (P) vs Amount of Gas (n)
Formula
## Ideal Gas Law ### Formula **PV = nRT** Solving for P: **P = nRT / V** Where: - **P** = pressure (atm) - **V** = volume (L) - **n** = moles of gas - **R** = gas constant = 0.08206 L·atm/(mol·K) - **T** = temperature (K) The ideal gas law assumes no intermolecular forces and negligible molecular volume.
Esempio Risolto
1 mole of gas at 273.15 K (0°C) in 22.414 L.
- 01P = nRT / V
- 02P = (1)(0.08206)(273.15) / 22.414
- 03P = 22.414 / 22.414
- 04P = 1.000 atm
Domande Frequenti
When does the ideal gas law apply?
It works well at low pressures and high temperatures where gas molecules are far apart. It becomes inaccurate near condensation or at very high pressures.
What value of R should I use?
R = 0.08206 L·atm/(mol·K) for pressure in atm and volume in liters. R = 8.314 J/(mol·K) for SI units.
How do I convert Celsius to Kelvin?
Add 273.15. For example, 25°C = 298.15 K. Temperature in the ideal gas law must be in Kelvin.
