Homework Help: General Chemistry problem with conversion factors

  1. Jan 11, 2012 #1
    One cubic mile of sea water, with a density of 1.13 g/cm3 contains how many gallons and how many tons of sea water?

    1 cm3/.001 L
    3.785 L/1 gal
    1 kg/2.2046 lb
    5280 ft3=1 mi3

    1.13g/1cm3 X 2.2046 lb/1000 X 1 cm3/.001 L X 3.785/gal

    After this point I get a bit confused about how to proceed. Any help would be appreciated.
