Problem with density

  1. Sep 6, 2008 #1
    1. The problem statement, all variables and given/known data
    if an object weighs 20 grams in air but 3.5 grams in a liquid of density 1.7g/c,^3
    What is the density of the object?


    2. Relevant equations
    density=m/v


    3. The attempt at a solution
    v=20-3.5/1.7
    =9.7
    then, density would be;
    d=3.5/9.7
    =0.36
    Is that correct?

    This is good. (Units = cm^3, I presume.)
    Careful. What's the mass of the object?

    thanks, as usual!

    mass is a measure of matter not weight!
