what quantity of heat is required to vaporize 141 g of benzene at its boiling point 80.1 degrees celcius? heat of vaporization is 30.8 degrees celcius.

  • chemistry -

    heat=massbenzene*Hv

    YOur Hv is nonsense. Units can be Joules/kg, Joules/g, calories/gram, or such. degrees C isnot an acceptable unit for heat of vaporization.

  • chemistry -

    my mistake. it's kj/mol
