(b)If two liquid of equal masses and different densities are mixed together then density of mixture
$\rho = \frac{{2{\rho _1}{\rho _2}}}{{{\rho _1} + {\rho _2}}} = \frac{{2 \times 1 \times 2}}{{1 + 2}} = \frac{4}{3}$
$\rho = \frac{{2{\rho _1}{\rho _2}}}{{{\rho _1} + {\rho _2}}} = \frac{{2 \times 1 \times 2}}{{1 + 2}} = \frac{4}{3}$
