Homework Help: Chemistry

Posted by Hannah on Thursday, February 9, 2012 at 10:25pm.

The following information is given for ether, C2H5OC2H5, at 1atm:

boiling point = 34.6oC Hvap(34.6oC) = 26.5 kJ/mol
melting point = -116oC Hfus(-116oC) = 7.27 kJ/mol
specific heat liquid = 2.32 J/goC

At a pressure of 1 atm, what is H in kJ for the process of condensing a 33.7 g sample of gaseous ether at its normal boiling point of 34.6 oC

I am not sure how to start this

q = mass ether x delta Hvap = ?
I would convert 33.7g ether to mole and use that for mass which will match the unit for delta Hvap in kJ/mol. q will have units of kJ.
