Molar enthalpy
= Molar enthalpy
{title2=$h_{\rm m}=H/n$}
<Molar enthalpy> is <enthalpy> per <amount of substance> $n$, measured in $\mathrm{J\,mol^{-1}}$. With $u_{\rm m}=U/n$ and <molar volume> $v_{\rm m}=V/n$, $h_{\rm m}=u_{\rm m}+pv_{\rm m}$. Its fixed-<pressure> <temperature> derivative is the corresponding <molar heat capacity> $C_{p,\rm m}$, at fixed composition.
