JEE Mains · Chemistry · STD 11 - 1. Some basic concept of chemistry
If a substance ' \(A\) ' dissolves in solution of a mixture of ' \(B\) ' and ' \(C\) ' with their respective number of moles as \(n_A, n_B\) and \(n_C\), mole fraction of ' \(C\) ' in the solution is _______.
- A \(\frac{n_C}{n_A \times n_B \times n_C}\)
- B \(\frac{n_C}{n_A+n_B+n_C}\)
- C \(\frac{n_C}{n_A-n_B-n_C}\)
- D \(\frac{n_B}{n_A+n_B}\)
Answer & Solution
Correct Answer
