Solution Dilution Calculator
This calculator helps determine the volume relationships for solution dilutions.
You can enter any three known parameters to calculate the fourth:
· Stock concentration, final solution volume, and final concentration → calculate required stock volume
· Stock concentration, stock volume, and final concentration → calculate final solution volume
· Stock concentration, stock volume, and final solution volume → calculate final solution concentration
Stock and final concentrations can be entered in molarity, v/v, or w/v units for flexible use.
What is the Solution Dilution Calculator?
The Solution Dilution Calculator allows you to compute the volume relationships for preparing diluted solutions from a stock solution. It supports multiple concentration units including w/v, v/v, and molarity.
By entering any three known parameters, the calculator can determine the fourth, streamlining solution preparation and eliminating manual calculation errors. The tool also includes a database of thousands of compounds, so you can select a compound directly without searching for its molecular weight.
Why Use This Calculator?
Accurate dilution calculations are essential for reproducible experiments, proper stoichiometry, and correct solution concentrations. The calculator handles various scenarios including:
- w/v → Molarity、w/v or v/v dilution
- v/v → Molarity、w/v or v/v dilution
- Molarity → Molarity、w/v or v/v dilution
- Convenient compound selection:
Thousands of compounds are built-in, allowing selection without additional molecular weight lookup.
