Interpretation Introduction

Interpretation:

The given expression for density of a mixture is to be proven.

Concept Introduction:

For a mixture containing n components, the mass fraction of the component i

in the mixture is given as:

  xi=miinmi ........(1)

Here, mi is the mass of component i .

For a fluid, its density (ρ) is defined as:

  ρ=mV ........(2)

Here, m is the mass of the fluid and V is the volume of the fluid.

Density of a mixture (ρmixture) containing n

components is defined as:

  ρmixture=inmiinVi ........(3)
