How much energy (in kilojoules) is required to convert 280mL of diethyl ether at its boiling point from liquid to vapor if its density is 0.7138 g/mL?
Its heat of vaporization is +26.5 kJ/mol at its boiling point.

  • Chemistry -

    Use the density to convert mL ether to grams.
    Then q = mass x heat vaporization. You will need to change grams ether to moles or change heat vap to kJ/g. Watch the units.
