Calculation path

Calculate two-component mole fractions from component masses and molar masses. The page evaluates the displayed equation from your supplied values and presents both symbolic and substituted KaTeX working so the arithmetic can be checked.

Calculation path

x1=(m1/M1)/[(m1/M1)+(m2/M2)]

What you provide

What you provide

  • First component mass expressed in g, using the same scenario as the other inputs
  • First molar mass expressed in g/mol, using the same scenario as the other inputs
  • Second component mass expressed in g, using the same scenario as the other inputs
  • Second molar mass expressed in g/mol, using the same scenario as the other inputs

What you receive

What you receive

  • First component mole fraction from the stated equation
  • A symbolic formula plus substituted working with your values
  • Visible assumptions, field guidance, and an authoritative learning reference

Use boundary

Choose the maximum decimal places shown. This does not increase source accuracy.

The mixture contains only the two entered components and masses represent pure component amounts.

Use internally consistent units and retain extra precision when carrying the result into another calculation.
