The units of the universal gas constant
If
- the pressure
#P# is in atmospheres (atm), - the volume
#V# is in liters (L), - the moles
#n# is in moles (mol), - and temperature
#T# is in Kelvin (K),
then
In other scenarios with pressures of
There is a variation of the ideal gas law that uses the density of the gas with the equation
#PM = DRT# where
#M# is the molar mass in#"g/mol"# and#D# is the density of the gas in#"g/L"# .
Lastly, this video may help introduce you to the ideal gas law.
I hope this is helpful.
