3. Calculate the change in entropy when 10 mol of sodium chloride is heated in the temperature range from 273 to 1973 K, using the following reference data:

Phase transition TFP, K FP,
kJ/mol Heat capacity,
J/(molK)
Melting 1073 31.0 SR, tv = 45.94 16.3210-3T
SR, kike = 66.50
boiling 1738 170.3 SR, gas = 57.37 - 1.71105T-2
