Van der Waals constants (data page)

This list is incomplete; you can help by adding missing items. (April 2017)

The following table lists the Van der Waals constants (from the Van der Waals equation) for a number of common gases and volatile liquids.^[1]

To convert from ${\displaystyle \mathrm {L^{2}bar/mol^{2}} }$ to ${\displaystyle \mathrm {L^{2}kPa/mol^{2}} }$, multiply by 100.
To convert from ${\displaystyle \mathrm {L^{2}bar/mol^{2}} }$ to ${\displaystyle \mathrm {m^{6}Pa/mol^{2}} }$, divide by 10.
To convert from ${\displaystyle \mathrm {L/mol} }$ to ${\displaystyle \mathrm {m^{3}/mol} }$, divide by 1000.

1 J·m³/mol² = 1 m⁶·Pa/mol² = 10 L²·bar/mol²

1 L²atm/mol² = 0.101325 J·m³/mol² = 0.101325 Pa·m⁶/mol²

1 dm³/mol = 1 L/mol = 1 m³/kmol = 0.001 m³/mol (where kmol is kilomoles = 1000 moles)
