If two liquids of same masses but densities ${\rho _1}$ and ${\rho _2}$ respectively are mixed, then density of mixture is given by
  • A$\rho = \frac{{{\rho _1} + {\rho _2}}}{2}$
  • B$\rho = \frac{{{\rho _1} + {\rho _2}}}{{2{\rho _1}{\rho _2}}}$
  • C$\rho = \frac{{2{\rho _1}{\rho _2}}}{{{\rho _1} + {\rho _2}}}$
  • D$\rho = \frac{{{\rho _1}{\rho _2}}}{{{\rho _1} + {\rho _2}}}$
