The enthalpy of vaporization at 298 K for diethylether (C4H10C) is 26.0 kj/mol. How much heat would be required to vaporize 1.00 L of the ether at 298 K if its density is 0.714 g/L ?

A) 250 kj
B) 74.1 kj
C) 186 kj
D) 130 kj
E) 440 kj

  • chemistry - ,

    q = mass x heat vap
    You can get the mass from the density and volume.
