## 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.

计算示例
1 mole of gas at 273.15 K (0°C) in 22.414 L.
- P = nRT / V
- P = (1)(0.08206)(273.15) / 22.414
- P = 22.414 / 22.414
- P = 1.000 atm
