Question

Equal masses of water and a liquid of density 2 g / c c are mixed together, then the mixture has a density of (A) (2/3 ) g/cc (B) (4/3)g/cc (C) (3/2) g/cc (D) 3 g/cc

If two liquids of equal masses and different densities are mixed together then the density of the mixture is ρ =(2 ρ 1 ρ 2/ρ 1 + ρ 2) ρ =(2 × 1 × 2/1 + 2)=(4/3) ρ =(4/3)ââ g/cc

Q. Equal masses of water and a liquid of density $2 g / cc$ are mixed together, then the mixture has a density of

$\frac{2}{3} g / cc$

$\frac{4}{3} g / cc$

$\frac{3}{2} g / cc$

$3 g / cc$

If two liquids of equal masses and different densities are mixed together then the density of the mixture is
$ρ = \frac{2 ρ _{1} ρ _{2}}{ρ _{1} + ρ _{2}}$
$ρ = \frac{2 \times 1 \times 2}{1 + 2} = \frac{4}{3}$
$ρ = \frac{4}{3} g / cc$
