**exam question.....**

Equal masses of two liquids of density P and 2P are mixed together thoroughly. Whats the density of the mixture provided the total volume remains constant?

1.4p/3 2. 3p/2 3. 3p 4.5p/3

im getting 4p/3..... is that correct?

One has m/[itex]\rho[/itex] = V, so m/[itex]2\rho[/itex] = V/2, based on equal masses, so

total mass = 2m, and total volume = V + V/2 = 3/2 V.
