Question

How much heat (in kJ) is evolved in converting 1.00 mol of steam at 160.0∘C to ice at -50.0∘C? The heat capacity of steam is 2.01 J/g⋅∘C and of ice is 2.09 J/g⋅∘C.

Answer 1

You also need to account for the energy of the phase change (i.e, vap->liquid, liquid->solid). Also you will need to covert either grams to moles or moles to grams so your unit will cancel.
