The formula to calculate the Mole Fraction (MF) is:
\[ MF = \frac{\text{Moles of Solute}}{\text{Moles of Solute} + \text{Moles of Solvent}} \]
Where:
The mole fraction can be defined as the number of moles of a solute divided by the total amount of moles of the solution. This can be seen in the equation given above. A mole fraction can be converted into a mole percent, or molar percentage, by multiplying the result of the mole fraction by 100. Unlike molar concentration, the mole fraction is a ratio of moles to moles. A molar concentration is a ratio of moles to volume.
Let's assume the following values:
Using the formula to calculate the Mole Fraction (MF):
\[ MF = \frac{\text{Moles of Solute}}{\text{Moles of Solute} + \text{Moles of Solvent}} = \frac{2}{2 + 8} = 0.2 \]
The Mole Fraction (MF) is 0.2.
