Summary

Calculate the mass percent of any component in a mixture by entering component mass and total mixture mass.

How it works

  1. Enter the mass of the component whose percent you want to find.
  2. Enter the total mass of the mixture (or add multiple components to compute the total automatically).
  3. Click Calculate to see the mass percent instantly.
  4. Switch to multi-component mode to break down a mixture into all its parts and see each component's weight percent.
  5. Use the Reverse Solver to find the component mass needed for a target mass percent.

Use cases

  • Determine the concentration of a solute in a solution (e.g., saline, sugar water).
  • Calculate the weight percent of an alloy component (e.g., carbon in steel).
  • Verify pharmaceutical formulation concentrations in compounding.
  • Compute nutrient or additive percentages in food manufacturing.
  • Find the percent composition of chemical reagents before a reaction.
  • Cross-check labeled concentrations on lab reagent bottles.
  • Solve stoichiometry and gravimetric analysis problems in coursework.
  • Calculate ingredient ratios in polymer blends or composite materials.
