Question : 5 of 75

Marks: +1, -0

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 gmL−1,C2 is the molarity and x2 is the mole fraction of the 2nd component, then C2 can be expressed as :

C2=
1000x2
M1+x2(M2−M1)
C2=
dx2
M2+x2(M2−M1)
C2=
dx1
M2+x2(M2−M1)
C2=
1000dx2
M1+x2(M2−M1)
