    We can use a simple equation to solve this problem.

    d = m/v

    Where d is the density, m is the mass and v is the volume.

    d = ?

    m = 87.47 mg = 87.47 x 10⁻³ g

    v = 0.03 mL

    By applying the equation,

    d = 87.47 x 10⁻³ g / 0.03 mL

    d = 2.92 g/mL

    Hence, the density of the mixture is 2.92 g/mL.
