  1. If you look up the heat of vaporization per gram (Joul/g):
    1. Change 1.5 moles of water to grams (multiply by 18.015 g/mol).
    2. (grams)(joules/gram) ---> joules
    3. joules / (joules/s) ---> seconds

    If you look up the molar heat of vaporization of water (joules/mol):
    1. (moles)(joules/mole) ---> joules
    2. joules / (joules/s) ---> seconds
