Mole Fraction Solution

STEP 0: Pre-Calculation Summary

Formula Used

Mole Fraction = (Number of Moles of Solute)/(Number of Moles of Solute+Number of Moles of Solvent)
X = (n)/(n+N)
This formula uses 3 Variables

Variables Used

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.
Number of Moles of Solute - (Measured in Mole) - The number of Moles of Solute is the total number of representative particles present in the solute.
Number of Moles of Solvent - (Measured in Mole) - Number of Moles of Solvent is the total number of representative particles present in the solvent.

STEP 1: Convert Input(s) to Base Unit

Number of Moles of Solute: 3.4483 Mole --> 3.4483 Mole No Conversion Required
Number of Moles of Solvent: 5.2 Mole --> 5.2 Mole No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

X = (n)/(n+N) --> (3.4483)/(3.4483+5.2)

Evaluating ... ...

X = 0.398725761132246

STEP 3: Convert Result to Output's Unit

0.398725761132246 --> No Conversion Required

FINAL ANSWER

0.398725761132246 ≈ 0.398726 <-- Mole Fraction

FAQ

What is 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 and is represented as X = (n)/(n+N) or Mole Fraction = (Number of Moles of Solute)/(Number of Moles of Solute+Number of Moles of Solvent). The number of Moles of Solute is the total number of representative particles present in the solute & Number of Moles of Solvent is the total number of representative particles present in the solvent.

How to calculate 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 is calculated using Mole Fraction = (Number of Moles of Solute)/(Number of Moles of Solute+Number of Moles of Solvent). To calculate Mole Fraction, you need Number of Moles of Solute (n) & Number of Moles of Solvent (N). With our tool, you need to enter the respective value for Number of Moles of Solute & Number of Moles of Solvent and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
