Volume occupied by one mole of a substance (chemical element or chemical compound) at a given pressure and temperature :
V_m(p, T) = \frac{V}{\nu} =\frac{M}{\rho}= \frac{1}{\rho_m} = \frac{N_A}{n} |
where
volume | molar mass of a substance | Molecular Concentration | |||
amount of substance | density of a substance | Avogadro constant (6.022140758(62) · 1023 mol−1 ) |
SI Unit | Oil Metric Unit | Oil Field Unit |
m3/ mol | m3/ mol | m3/ mol |
Molar volume is inverse to Molar Density :
V_m = \frac{1}{\rho_m} |
In case of fluid which satisfies Real Gas EOS @model the Molar volume can be expressed in terms of Z-factor :
V_m = \frac{ZRT}{p} |
where
temperature | |
pressure | |
gas constant |
Molar volume of the mixture is:
V_m(p, T) =\frac{M}{\rho_f} = \frac{\sum_k M_k \cdot x_k}{\rho_f} |
molar mass of the k-th mixture component | |
mole fraction of the k-th mixture component | |
