If two liquids of same volume but different densities \[{{\rho }_{1}}\] and \[{{\rho }_{2}}\] are mixed, then density of mixture is given by

\[\rho =\frac{{{\rho }_{1}}+{{\rho }_{2}}}{2{{\rho }_{1}}{{\rho }_{2}}}\]

\[\rho =\frac{{{\rho }_{1}}+{{\rho }_{2}}}{2}\]

\[\rho =\frac{2{{\rho }_{1}}{{\rho }_{2}}}{{{\rho }_{1}}+{{\rho }_{2}}}\]

\[\rho =\frac{{{\rho }_{1}}{{\rho }_{2}}}{{{\rho }_{1}}+{{\rho }_{2}}}\]
