Molarity into Mole Fraction
$M = n_2/V$
$x_2 = \frac{n_2}{n_2 + n_1}$
Mass of solution: $M_1n_1 + M_2n_2$
Volume: $M_1n_1 + M_2n_2/ \rho$
Let moles of solution be 1, i.e., $n_1 + n_2 = 1$.
$M = \frac{x_2\rho} {M_1(1-x_2) + M_2x_ …

Molarity into Mole Fraction
So, recently, I was solving a question wherein I had to find out an equation connecting mole fraction to molarity.
We have to express the mole fraction of the solute ($x_2$) in terms of molarity (M), …
