Express volume expansivity in terms of density

  1. Jan 22, 2017 #1
    1. The problem statement, all variables and given/known data
    Express volume expansivity (B) in terms of density (ρ) and its partial derivatives
    2. Relevant equations
    B = (1/V) (dV/dT)
    V = m/ρ

    3. The attempt at a solution
    I have only managed to substitute m/ρ into the expansivity equation.
    Don't really understand how to manipulate the differential equation into (-1/ρ)(dρ/dT)

    Especially the part where d[(m/ρ)]/(m/ρ) equals (-1/ρ)dρ

    What are the properties of "m?"
