Question

Equal masses of water and a liquid of density 2 are mixed together the density of mixture is

Answer 1

Mass of water = m

Density of water = 1 g/cc

Density = mass/volume

So, volume of water = m cm³

Mass of liquid = m

Density of liquid = 2

Density = mass/volume

So, volume of water = m/2 cm³

Total mass = 2m

Total volume = m + m/2

                      = 3m/2

Density = mass/volume

             = 2m / (3m/2)

             = 4/3

             = 1.33 g/cc

Hope this helps! :)

Answer 2

Answer:4/3

Explanation:we known

Rho= 2 rho1 rho2/ rho 1 + rho 2

Density of water is 1

Density of liquid is 2 given

Potting these value on formula

2×1×2/1+2 = 4/3
