63. Calculate the change in entropy during the heating of 1 mole of mercury from -77 ° C to 25 ° C. The heat of fusion of mercury at t = -38.9 ° C is 11.58 J g-1; the specific heat of solid mercury St = 0.138 J g-1 K-1, liquid mercury C = 0.140 - 2.86 10 -6 T J g-1 K-1. The atomic weight of mercury is 200.6.
