Chemistry calculator
Dilution Calculator
Use C1V1 = C2V2 to estimate final concentration and diluent volume.
Formula
Dilution formula
Use appropriate lab safety, measurement precision, and protocol rules for real solutions.
C1V1 = C2V2
25 mL of 10x stock diluted to 250 mL gives 1x final concentration.
FAQs
Do concentration units matter?+
Use the same concentration unit for stock and final concentration.
What is diluent?+
Diluent is the added liquid needed to reach final volume.
How does the Dilution Calculator calculate the result?+
It uses the Dilution formula: C1V1 = C2V2. 25 mL of 10x stock diluted to 250 mL gives 1x final concentration.
What information do I need to use the Dilution Calculator?+
Use C1V1 = C2V2 to estimate final concentration and diluent volume.
How accurate is the Dilution Calculator?+
Dilution Calculator applies the formula and assumptions shown on this page. Results may be rounded for readability, so verify changing rates, thresholds, medical guidance, or legal rules with the cited source or a qualified professional.
What should I check before using the Dilution Calculator result?+
Check that the units, dates, rates, and assumptions match your situation. Change one input at a time to understand which values have the largest effect on the result.
