number of moles
The ideal gas equation \(PV = \mu RT\) relates the pressure P, volume V and absolute temperature T of a gas, where R is the universal gas constant.
Here μ is the amount of substance expressed as the number of moles of gas present, so that PV has units of energy consistent with μ (in moles) multiplied by R (in J/mol·K) and T (in kelvin). It is not the number of molecules (that would require Avogadro's number as a separate factor), nor the specific heat ratio or coefficient of friction, which are unrelated dimensionless quantities.
Hence, μ represents the number of moles of the gas.
