A solution of two components containing n 1 moles of the 1 st component and n 2 moles of the 2 nd component is prepared. M 1 and M 2 are the molecular weights of component 1 and 2 respectively. If d is the density of the solution in gmI - 1 , C 2 is the molarity and x 2 is the mole fraction of the 2 nd component, then C 2 can be expressed as :

Options

  1. AC 2 = 1000 x 2 M 1 + x 2 M 2 - M 1
  2. BC 2 = dx 2 M 1 + x 2 M 2 - M 1
  3. CC 2 = 1000 dx 2 M 1 + x 2 M 2 - M 1
  4. DC 2 = dx 1 M 2 + x 2 M 2 - M 1

Correct answer

C. C 2 = 1000 dx 2 M 1 + x 2 M 2 - M 1

Step-by-step solution

C 2 = 1000 dx 2 M 1 + x 2 M 2 - M 1
