The composition of a liquid with suspended solid particles is generally characterized by the fraction of solid particles either by weight or mass, C_{s, mass} = m_s/m_m or by volume, C_{s, vol} = V_s/V_m where m is mass and V is volume. The subscripts s and m indicate solid and mixture, respectively. Develop an expression for the specific gravity of a water based suspension in terms of C_{s, mass} and C_{s, vol}.
