## 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.
हल किया गया उदाहरण
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
अक्सर पूछे जाने वाले प्रश्न
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.
