A solution of two components containing `n_1` moles of `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 g` mL^(-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

A. `C_2 =(1000 x_2)/(M_1 + x_2 (M_2 - M_1))`
B. `C_2 =(d x_2)/(M_1 + x_2 (M_2 - M_1))`
C. `C_2 =(1000d x_2)/(M_1 + x_2 (M_2 - M_1))`
D. `C_2 =(d x_1)/(M_2 + x_2 (M_2 - M_1))`
