How Do You Calculate A Mole Fraction?
In chemistry the term mole fraction refers to the ratio of the moles of a component of a solution to the total moles of all of components present. A fraction is always the part over a whole. If you would like to determine the percentage that your given solute composes you will take the mole fraction and multiply by 100. Step 1 Determine how many moles of solute “A” are present in the solution. Step 2 Determine how many total moles are present in your solution. Include the moles in your solute “A” in the total. Step 3 Divide the amount of moles in your solute “A” by the sum of the total number of moles. The quotient is called the mole fraction.
