Easy MCQ +4 / -1 PYQ · JEE Mains 2024

If a substance '$A$' dissolves in solution of a mixture of '$B$' and '$C$' with their respective number of moles as $\mathrm{n}_{\mathrm{A}}, \mathrm{n}_{\mathrm{B}}$ and $\mathrm{n}_{\mathrm{C}_3}$. Mole fraction of $\mathrm{C}$ in the solution is

  1. A $\frac{n_C}{n_A \times n_B \times n_C}$
  2. B $\frac{n_B}{n_A+n_B}$
  3. C $\frac{n_C}{n_A+n_B+n_C}$ Correct answer
  4. D $\frac{n_C}{n_A-n_B-n_C}$

Solution

<p>Mole fraction of $\mathrm{C=\frac{n_C}{n_A+n_B+n_C}}$</p>
