Homework Help: Difference in Magnitudes between two densities

  1. Feb 18, 2010 #1
    1. The problem statement, all variables and given/known data

    the question is to find the difference in magnitudes between the density of water which 0.995 and density of NaCl which is 1.0499

    3. The attempt at a solution
    when speaking about the difference, I simply minus 1.0499 from 0.995

    since magnitude means distance and displacement . I found the slopes of mass and volume of my graph which gave me the densities of both solutions

    just want to know if im on the right track

    Can you post the complete and correct text? It does not make too much sense as it is.
    And density of NaCl is not 1.05 but something over 2. Maybe it's about a NaCl solution?
