If two liquids of same volume but different densities ρ1 and ρ2 are mixed, then density of mixture is given by

Question

If two liquids of same volume but different densities ρ1 and ρ2 are mixed, then density of mixture is given by (A) ρ=(ρ1+ρ2/2) (B) ρ=(ρ1+ρ2/2 ρ1 ρ2) (C) ρ=(2 ρ1 ρ2/ρ1+ρ2) (D) ρ=(ρ1 ρ2/ρ1+ρ2)

Correct answer is (a) ρ=(ρ1+ρ2/2)

Q. If two liquids of same volume but different densities $ρ_{1}$ and $ρ_{2}$ are mixed, then density of mixture is given by

$ρ = \frac{ρ _{1} + ρ _{2}}{2}$

$ρ = \frac{ρ _{1} + ρ _{2}}{2 ρ _{1} ρ _{2}}$

$ρ = \frac{2 ρ _{1} ρ _{2}}{ρ _{1} + ρ _{2}}$

$ρ = \frac{ρ _{1} ρ _{2}}{ρ _{1} + ρ _{2}}$

Correct answer is (a) $ρ = \frac{ρ _{1} + ρ _{2}}{2}$

Q. If two liquids of same volume but different densities ρ1​ and ρ2​ are mixed, then density of mixture is given by

ρ=2ρ1​+ρ2​​

ρ=2ρ1​ρ2​ρ1​+ρ2​​

ρ=ρ1​+ρ2​2ρ1​ρ2​​

ρ=ρ1​+ρ2​ρ1​ρ2​​
