How to use the Solution Mass Percent Calculator
Enter masses in the same unit. The denominator includes both solute and solvent; it is not solute divided by solvent alone.
The calculation
Mass percent = solute/(solute + solvent) × 100
Worked example
10 g solute with 90 g solvent forms 100 g total solution at 10% by mass.
Assumptions and limits
No volume percent, molarity, density, reaction or material compatibility is inferred. Combined mass must be positive.
