Answer 2

Answer:

Take V volume of water.

So, we have V\rhoVρ mass of water.

Take V volume of the liquid as well (we're instructed to do that).

So, 1.5\rho V1.5ρV mass of liquid.

Total mass = 2.5\rho V2.5ρV , and total volume = 2V2V .

So, final relative density = 1.25 (total mass / (total volume * density of water))
