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.

    1. P = nRT / V
    2. P = (1)(0.08206)(273.15) / 22.414
    3. P = 22.414 / 22.414
    4. P = 1.000 atm
