  1. The following molar volumes and densities for the majority of the gaseous elements were calculated from the van der Waals equation of state, using the quoted values of the van der Waals constants.

  2. The table below lists density of different metals including common metals and less common metals in g/cm3, kg/m3, lb/in3, lb/ft3.

  3. USEFUL TABLES AND CHARTS A.1 USEFUL PROPERTY DATA FOR CORRESPONDING STATES ESTIMATES The values given in Table A.1 are useful in “corresponding states” estimates of thermodynamic properties. Bar¼ 0.987atm. Physical and Chemical Equilibrium for Chemical Engineers, Second Edition. Noel de Nevers.

  4. The atomic number density (N; atoms/cm 3) of a pure material having atomic or molecular weight (M; grams/mol) and the material density (⍴; gram/cm 3) is easily computed from the following equation using Avogadro’s number (N A = 6.022×10 23 atoms or molecules per mole):

  5. Material density is given by $ \rho =m/V$, where $m$ is mass and $V$ is volume. Again number density given by $n=N/V$, where $N$ is the total number of particle. How can I calculate number density $n$ from material density $ \rho $.
