Two immiscible of densities 2.5g//cm^(3)...

Two immiscible of densities `2.5g//cm^(3)` and `0.8g//cm^(3)` are taken in the ratio of their masses as `2:3` respectively find the average density of the liquid conbination.

Text Solution

Verified by Experts

Let masses be 2m g & 3m, g, then `V=V_(1)+V_(2)=((2m)/(2.5)+(3m)/(0.8))cm^(3)`
total mass `=2m+3m+5mg`
therefore the average desity `rho=(5m)/(V)=(5m)/((2m)/(2.5)+(3m)/(0.8))=(5)/((2)/(2.5)+(3)/(0.8))=(10)/(9.1)gm//cm^(3)=1.09gm//cm^(3)`
