Question

Calculate the molar entropy of vaporization for liquid hydrogen iodide at its boiling point -34.55 degrees celcius. HI(l) <=> HI(g) 
deltaHvap = 19.76 kJ/mol

DrBob222 · Answer

delta Hvap = Tvap x delta Svap Substitute and solve for delta Svap. Don't forget Tvap must be in kelvin. Note the correct spelling of celsius.

didn't help me much :? anyone else?

DrBob222 · Answer

You can't substitute 19.76 for delta Hvap and divide by -34.55 C (in kelvin, of course) to arrive at DSvap? You must want someone to punch the calculator for you.
