Determine the entropy change when 7.40 mol of HCl(l) boils at atmospheric pressure. I already have the delta Sfus(12.5 J/Kmol) and delta Svap(93.2 J/Kmol), I just cant seem to figure out the last part.
Is this part of a problem and there is more to post? It appears to me you are have delta S vap and that x 7.40 will do it. But I may be confusing it with something else. If you have more to the problem please post it.
