atm vs moles per liter

[Ryka Vahidi 1E]

When are you supposed to calculate partial pressure in terms of atm vs mol/liter? And does it make a difference which unit you use?

[Larne Reyes 1A]

We only use atm or bar when we use partial pressures for gases only. We use mol/L for molar concentrations for both gases and aqueous solutions in relation to the equilibrium constant. There shouldn't be a difference when using partial pressures or molar concentrations for gases.

[Baria Alaswad 2E]

Use atm for gases and mol/L for solutions. The choice affects equilibrium constants (Kp for gases in atm, Kc for solutions in mol/L), impacting the results of your calculations.

Use PV = nRT to calculate the individual pressure of each gas in a mixture

Hi, partial pressure is typically computed in atm, while harder scientific calculations are done in moles per liter (mol/L). The choice of unit does not affect the value, but rather is determined by context and convenience.
