Two liquids of densities `2 rho " and " rho` having their volumes in the ratio `3 : 2` are mixed together. Density of the mixture will be

A

`(2rho)/(3)`

B

`rho/2`

C

`(8rho)/(5)`

D

`(4rho)/(5)`

Text Solution

Verified by Experts

The correct Answer is:
C
`rho=("Total mass")/("Total volume") = (rho_1V_1 + rho_2V_2)/(V_1 + V_2) = ((2rho) +( rho) (2//3))/(1+2//3) = (8rho)/(5)`
