The derived values of vapor-pressures for selected isotherms are presented in Table 3. The uncertainty in derived values of p s is good enough (within 0.1–0.2%) because the experimental p–ρ isotherms are almost linear and the range of extrapolation is very small (maximum is within 0.1–0.4 MPa). Therefore, the extrapolation is very reliable.
