Calculate the Entropy Change $\triangle_{vap} S^{∘}$ , J K^-1 Mol^-1) When 1

Multiple Choice

Calculate the entropy change ( $\triangle_{vap} S^{∘}$ , J K^-1 mol^-1) when 1.00 mol of mercury at its boiling point (T_b = 356.55 °C) vaporizes (in the process the temperature does not change, $\triangle_{vap} H^{∘}$ for mercury is + 59.3 kJ mol^-1) .
