Equal masses of two substance of densities `rho_(1) and rho_(2)` are mixed together. What is the density of the mixture?

Equal masses of two substances of densities p_1 and p_2 are mixed together. The density of mixture would be

If equal masses of two liquids of densities d_(1) and d_(2) are mixed together, the density of the mixture is

If equal masses of two liquids of densities d_(1) and d_(2) are mixed together, the density of the mixture is

(i) Prove that the density of the mixture of two substances with densities rho_(1)andrho_(2) of equal mass will be (2rho_(1)rho_(2))/(rho_(1)+rho_(2)) . (ii) Prove that if the two substance with densities rho_(1)andrho_(2) are mixed in equal volumes, then the density of the mixture thus formed will be 1/2(rho_(1)+rho_(2))

Two substances of densities rho_(1) and rho_(2) are mixed in equal volume and the relative density of mixture is 4 . When they are mixed in equal masses, the relative density of the mixture is 3. the values of rho_(1) and rho_(2) are:

Two substances of densities rho_(1) and rho_(2) are mixed in equal volume and the relative density of mixture is 4 . When they are mixed in equal masses, the relative density of the mixture is 3. the values of rho_(1) and rho_(2) are:

If two liquids of same volume but different densities rho_1 and rho_2 are mixed, then the density of the mixture is:
