At 10 k cp, m(hg(s)) = 4.64 j k−1 mol−1. between 10 k and the melting point of hg(s), 234.3 k, heat capacity measurements indicate that the entropy increases by 57.74 j k−1 mol−1. the standard enthalpy of fusion of hg(s) is 2322 j mol−1 at 234.3 k. between the melting point and 298.0 k, heat capacity measurements indicate that the entropy increases by 6.85 j k−1 mol−1. determine the third-law standard molar entropy of hg(l) at 298 k.
