Question

Equal mass of water and a liquid of relative density 2 are mixed together. what will be relative density of the mixture

Answer 1

Explanation:

let mass of liquid and water be x gm .

density of water = 1 gcm

−3

Relative density =

ρ

(

water)

ρ

(

liquid)

= 2

so density of liquid = 2 gcm

−3

Volume of water =

1

x

cc = x cm

3

Volume of liquid =

2

x

cm

3

hence total volume =

2

3x

total mass x + x = 2x

hence density of mixture = 3x×.5

2x

=
