Here is how the Mole Fraction equation looks like.

0.3987 = \frac{3.4483}{3.4483 + 5.2}

0.3987 = \frac{3.4483mol}{3.4483mol + 5.2mol}

0.3987 = \frac{3.4483}{3.4483 + 5.2}

Mole Fraction Solution

Follow our step by step solution on how to calculate Mole Fraction?

FIRST Step Consider the formula

X = \frac{n}{n + N}

Next Step Substitute values of Variables

∴

X = \frac{3.4483mol}{3.4483mol + 5.2mol}

Next Step Prepare to Evaluate

∴

X = \frac{3.4483}{3.4483 + 5.2}

Next Step Evaluate

∴

X = 0.398725761132246

LAST Step Rounding Answer

∴

X = 0.3987

How to Evaluate Mole Fraction?

Mole Fraction evaluator uses Mole Fraction = (Number of Moles of Solute)/(Number of Moles of Solute+Number of Moles of Solvent) to evaluate the Mole Fraction, Mole fraction represents the number of molecules of a particular component in a mixture divided by the total number of moles in the given mixture. Mole Fraction is denoted by X symbol.

How to evaluate Mole Fraction using this online evaluator? To use this online evaluator for Mole Fraction, enter Number of Moles of Solute (n) & Number of Moles of Solvent (N) and hit the calculate button.

FAQs on Mole Fraction

What is the formula to find Mole Fraction?

The formula of Mole Fraction is expressed as Mole Fraction = (Number of Moles of Solute)/(Number of Moles of Solute+Number of Moles of Solvent). Here is an example- 0.398726 = (3.4483)/(3.4483+5.2).

How to calculate Mole Fraction?

With Number of Moles of Solute (n) & Number of Moles of Solvent (N) we can find Mole Fraction using the formula - Mole Fraction = (Number of Moles of Solute)/(Number of Moles of Solute+Number of Moles of Solvent).
