Evidence from the paper

The simulated molar volume V0 (=24.414 cm3/mol) agrees well with the results of Yeganeh-Haeri [16] (within 0.1%) under 300 K at zero pressure.

Additional notes

note
V0 obtained from MD simulation at 300 K and zero pressure; no explicit analytical EOS form (e.g. Birch-Murnaghan) stated. Simulated P-V relation at 300 K agrees with experimental data over >100 GPa range (Fig. 1).
