There's a mistake in Sample Exercise 19.2 in the eText.  They give
del(H_fus) as - 2.29 kJ/mol.  That's not possible.  Enthalpies of fusion
are always positive.  By definition it's the heat required to melt one mole
of the solid.  It should be + 2.29 kJ/mol.  It is correct in the paper version
of the book.

The del(H_freezing) = - del(H_fus) = - (2.29 kJ/mol) = - 2.29 kJ/mol
