Concentration - Mole Fraction

Question 1

What is the Mole Fraction?

Answer 1

The combination of all components of a mixture divided by the amount of moles combined.

X(a)=n(a)/(n(a)+n(b)). (moles fraction = moles solute/total moles in solution). Percentages are out of 100 grams.

Mole fraction of “a” in a mixture of “a and b.”

Question 2

Moles solute = Moles fraction * total moles in solution

Answer 2

Moles solute = Moles fraction * total moles in solution
