Homework Help: Specific Gravity and antifreeze

  1. Jan 13, 2008 #1
    1. The problem statement, all variables and given/known data
    If 5.0L of antifreeze solution (0.8 specific gravity) is mixed with 4L of water to make a 9.0 L mixture. what is the specific gravity of the mixture?

    2. Relevant equations
    SG = density of substance / density of water

    3. The attempt at a solution
    I am confused as in how to gain the density from the substance gravity. Is it given that the density is 1 g/cm^3 for water?

    Use CGS system -- there the specific gravity is numerically equal to the density in gm/cc.
    1 L = 1000 cc = 1000 mL.
