Define the mole fraction of a substance in solution.

Question 1

Define the mole fraction of a substance in solution.

Question 2

Mole fraction: Mole fraction of a constituent (solute as well as solvent) is the fraction obtained by dividing number of moles of that constituent by the total number of moles of all the constituents present in the solution. In a binary mixture, there are two components A and B and their moles are n_A and n_B respectively. If their mole fractions are x_A and x_B

If the mass of A and B are W_A and W_B respectively and their molar masses are M_A and M_B then,
n_A = \(\frac { { W }_{ A } }{ { M }_{ A } } \)
n_B = \(\frac { { W }_{ B } }{ { M }_{ B } } \)

The sum of mole fractions of all the components are always equal to 1.
X_A + x_B = 1
