SOLUTION CALCULATOR · v3.0 PRECISION · 6 DECIMALS

Mole Fraction · Solution Volume Calculator

Precisely calculate mole fractions and required volumes for multi-component solutions based on molecular weight and density. Supports up to 5 components.

STEP 01

Molecule Parameters

Set molecular weight and density for each component

Unit mapping: Moles (mol) → Volume (mL) → Weight (g)
STEP 02

Calculation Series

Enter A's mole fraction and moles, then enter intermediate fractions. The last component is auto-calculated.

Formulas

Total Moles
ntotal = nA / XA
Component Moles (i)
ni = ntotal × Xi
Last Component Fraction
Xlast = 1 − Σ Xothers
Volume (i)
Vi = (ni × MWi) / ρi
Weight (i)
Wi = ni × MWi
