Homework Help: Did I work this problem correctly?

  1. Jan 11, 2009 #1
    Question:

    The mass of a container filled with liquid mercury is 244.0 g, and the mass of the empty container is 110.2 g

    a. What is the volume of the container? (density of mercury = 13.546 g/ml)

    b. The same container is filled with a second liquid, and the mass of the filled container is 114.9 g. What is the density of the second liquid?



    My answers:

    a)

    244.0 g - 110.2 g = 133.8 g
    133.8 g/(13.546 g/mL) = 9.877 mL


    b)

    114.9 g - 110.2 g = 4.7 g
    4.7 g/9.877 mL = 4.8x10 g/mL



    Does that look right? if not where did I go wrong?

    I appreciate the help....
