Question:
What is the mole fraction of sodium chloride in solution that is 13.0% by mass sodium chloride and that has a density of 1.10 g/mL?
Mole Fraction:
The mole fraction of a substance in a mixture/solution describes how much of a substance is present when compared to the whole mixture/solution. Often we are given mass of a solute and volume of the solution. To work with these given units, we will need the molar masses of solute and solvent and the density of the solution.
