The Formula
The formula set draws on the core dilution equations and computes each answer from the generated values.
C₁V₁ = C₂V₂DF = V_final / V_aliquotCₙ = C₀ / Fⁿ- C / V:
- Concentrations and volumes generated per problem
- DF / F:
- Dilution and step factors
A basic sheet with 10 problems includes items such as "How much 2 M NaCl makes 250 mL of 0.5 M?" with the key answer 62.5 mL and the worked step V₁ = 0.5 × 250 / 2.
Conversion Table
The conversion table shows 6 sample problems, 1 from each topic family, with key answers.
| Topic | Sample problem | Key answer |
|---|---|---|
| C₁V₁ = C₂V₂ | How much 2 M NaCl makes 250 mL of 0.5 M? | 62.5 mL |
| Dilution factor | 10 µL into 990 µL gives what DF? | 100 |
| Serial dilution | Three 1:10 steps from 10⁸ cells/mL give what? | 10⁵ cells/mL |
| Ratio conversion | 1:4 stock-to-diluent equals what stock-to-final ratio? | 1:5 |
| Percent solution | Grams of glucose for 500 mL of 5% w/v? | 25 g |
| Back-calculation | A 1:20 diluted sample reads 3.2 mg/L. Original? | 64 mg/L |
What Is the Dilution Worksheet Generator?
The Dilution Worksheet Generator is a tool that produces sets of dilution calculation exercises with matching answer keys, at a chosen difficulty and topic mix. Each worksheet draws random values within realistic lab ranges, so every copy is unique.
Practice sheets build calculation fluency for chemistry, biology, and nursing students. The generator covers 6 topic families: C₁V₁ = C₂V₂, dilution factor, serial dilution, ratio conversion, percent solutions, and back-calculation. Answer keys show the formula and the worked steps for each problem.
