If a substance ' AA ' dissolves in solution of a mixture of ' BB ' and ' CC ' with their respective number of moles as nA,nB\mathrm{n}_{\mathrm{A}}, \mathrm{n}_{\mathrm{B}} and nC3\mathrm{n}_{\mathrm{C}_3} . Mole fraction of C\mathrm{C} in the solution is

Multiple Choice Options

  • A nCnA×nB×nC\frac{n_C}{n_A \times n_B \times n_C}
  • B nBnA+nB\frac{n_B}{n_A+n_B}
  • C nCnA+nB+nC\frac{n_C}{n_A+n_B+n_C}
  • D nCnA−nB−nC\frac{n_C}{n_A-n_B-n_C}

Step-by-Step Verified Solution

Mole fraction of C=nCnA+nB+nC\mathrm{C=\frac{n_C}{n_A+n_B+n_C}}
