Concentration after dilution
0.1 mol/L
Diluent to add
9 mL
Percent of original strength
10 %
What this calculator does
Calculates the dilution factor between a stock solution and the diluted solution prepared from it.
What your result means
A dilution factor of 10 means the diluted solution is one tenth the strength of the stock.
Formula and working
DF = V_final ÷ V_stock = C_stock ÷ C_final
- 1
Collect the inputs
Volume of stock taken (V_stock) = 1 mL; Final volume after dilution (V_final) = 10 mL; Concentration of the stock (C_stock) = 1 mol/L
- 2
Apply the formula
DF = V_final ÷ V_stock = C_stock ÷ C_final
- 3
Result
Dilution factor = 10 ×
Frequently asked questions

- Dilution factor, dimensionless
- V_final
- Final volume of diluted solution
- V_stock
- Volume of stock taken
- • Volumes are additive.
- • The final volume is the total volume after making up, not the diluent added.
