The enthalpy change of fusion of mercury is 2331 J mol−1. Find ∆H for converting 100.0 g of solid mercury at −75.0◦C to liquid mercury at 25.0◦C at a constant pressure of 1.000 atm. Assume that the heat capacities are constant and equal to their values in Table A.6 of the appendix.

Consider liquid mercury (Hg (l)). Look up values for k (kappa)and B (beta). The constant pressure heat capacity in the liquidrange is given by the expression Cp = A + BT


where A = 10 J/mol*K and B = 0.12 J/mol*K^2


The density of mercury is 13.5 g/mL


Calculate the total change in Enthalpy (delta H) if you heat 25grams of mercury liquid from 25 degrees celsius to 75 degreescelsius and also increase the pressure from 1 bar to 75 kbar
