We can use the formula below to determine the entropy change(ΔS):
where ΔHfus is the heat of fusion
T is the temperature in Kelvin (K)
Recall:
1 kJ = 103 J
Calculate the change in entropy that occurs in the system when 45.0 g of acetone (C3H6O) freezes at its melting point (-94.8 ˚C). ΔHfus = 5.69 kJ/mol.
