Properties Of Solids And Liquids Question 299

Question: If two liquids of same masses but densities $ρ_{1}$ and $ρ_{2}$ respectively are mixed, then density of mixture is given by

Options:

A) $ρ = \frac{ρ_{1} + ρ_{2}}{2}$

B) $ρ = \frac{ρ_{1} + ρ_{2}}{2 ρ_{1} ρ_{2}}$

C) $ρ = \frac{2 ρ_{1} ρ_{2}}{ρ_{1} + ρ_{2}}$

D) $ρ = \frac{ρ_{1} ρ_{2}}{ρ_{1} + ρ_{2}}$

Show Answer

Answer:

Correct Answer: C

Solution:

$ρ = \frac{Total mass}{Total volume} = \frac{2 m}{V_{1} + V_{2}} = \frac{2 m}{m (\frac{1}{ρ_{1}} + \frac{1}{ρ_{2}})}$ $ρ = \frac{2 ρ_{1} ρ_{2}}{ρ_{1} + ρ_{2}}$
