    1. The problem statement, all variables and given/known data
    The density of mercury is 13 600 kg m^-3. What is this in g cm^-3


    3. The attempt at a solution
    I dont know where to begin. Please show me how and why rather than just give me the answer! Thank you! X

    Do you know how many cm there are in 1 m, and how many grams there are in 1 kg?

    1 kg = ? g
    1 m = ? cm

    ( 1**3 ) ( m**3 ) = ( ? )**3 (cm**3) ( take third power of both sides )

    1 kg = ? g
    1 m**3 = (?)**3 (cm**3)

    then divide
