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.

    Welcome to the PF.

    I give some tips for unit conversions in this thread:

    Just write out the quantity you have now, and keep multiplying by "1" to do each part of the units conversion. Can you give that a try and show us your work? Carry the units along in numerator and denominator of your quantity as you go...
