Percent Solution Calculator
Calculate mass/volume, mass/mass, and volume/volume percentages for chemical solutions
Calculate Solution Concentration
Mass of solute per volume of solution
Weight of the dissolved substance
Total volume of the final solution
Formulas Used
Mass/Volume %: (mass of solute in g ÷ volume of solution in mL) × 100
Mass/Mass %: (mass of solute ÷ mass of solution) × 100
Volume/Volume %: (volume of solute ÷ volume of solution) × 100
Parts per Million: % (w/v) × 10,000
Example Calculation
Sugar Solution Example
Goal: Calculate concentration of sugar solution
Given: 7.8 g of sugar dissolved in 62 mL of solution
Type: Mass/Volume percent (w/v%)
Step-by-Step Solution
1. Formula: % (w/v) = (mass of solute ÷ volume of solution) × 100
2. Substitute values: % (w/v) = (7.8 g ÷ 62 mL) × 100
3. Calculate: % (w/v) = 0.1258 × 100
Result: 12.58% (w/v) sugar solution

Solution Tips
w/v% is most common for aqueous solutions
w/w% is independent of temperature
v/v% is used for liquid-liquid mixtures
Always specify which percentage type you're using
Use consistent units throughout calculations
Understanding Percent Solutions
What are Percent Solutions?
Percent solutions express the concentration of a solute in a solution as a percentage. There are three main types: mass/volume (w/v%), mass/mass (w/w%), and volume/volume (v/v%), each expressing concentration in different ways.
Applications
- •Medical and pharmaceutical preparations
- •Laboratory solution preparation
- •Quality control in manufacturing
- •Environmental monitoring
- •Food and beverage industry
Key Formulas
w/v% = (mass in g ÷ volume in mL) × 100
w/w% = (mass solute ÷ mass solution) × 100
v/v% = (volume solute ÷ volume solution) × 100
When to Use Each Type
- w/v%: Most common, especially for aqueous solutions
- w/w%: When precise mass ratios are needed
- v/v%: For liquid-liquid mixtures (alcohols, etc.)
Remember: Always specify which type of percentage you're reporting to avoid confusion.
