Question

A solution of two components containing n1 moles of the 1st component and n2 moles of the 2nd component is prepared. M1 and M2 are the molecular weights of component 1 and 2 respectively. If d is the density of the solution in g ml–1, C2 is the molarity and x2 is the mole fraction of the 2nd component, then C2 can be expressed as : (A) C2 = ) M M ( x M x d 2 2 (B) C2 = ) M M ( x M x 1 2 2 (C) C2 = ) M M ( x M x d 1 2 2 (D) C2 = ) M M ( x M x d 2 2
