How to use mole fraction calculator
- Enter or edit the example values in the input panel.
- Review the method below and choose the options that match your task.
- Run the tool, check the result, and copy or download it. Reset restores the example; Clear removes your input and result.
Method & assumptions
xᵢ = nᵢ / (nᵢ + n_other); total amount must be greater than zero.
Enter one component and the sum of all remaining components in moles. Do not use masses unless you first convert each material using its own molar mass.
Result units: Component mole fraction (dimensionless)
Worked example
