JEE Main 2024 (30 Jan, Shift 2) Chemistry Q61: Mole Concept

Question

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

Accepted Answer

Option 3: $\frac{\mathrm{n_C}}{\mathrm{n_A} + \mathrm{n_B} + \mathrm{n_C}}$

Answer

$\frac{\mathrm{n_B}}{\mathrm{n_A} + \mathrm{n_B}}$

Answer

$\frac{\mathrm{n_C}}{\mathrm{n_A} 	imes \mathrm{n_B} 	imes \mathrm{n_C}}$

Answer

$\frac{\mathrm{n_C}}{\mathrm{n_A} + \mathrm{n_B} + \mathrm{n_C}}$

Answer

$\frac{\mathrm{n_C}}{\mathrm{n_A} - \mathrm{n_B} - \mathrm{n_C}}$
