Short summary: A research-literacy explanation of C1 × V1 = C2 × V2 and documentation-friendly dilution notes.

The basic relationship
Dilution math connects a starting concentration, a target concentration, and a final volume. The common relationship is C1 × V1 = C2 × V2.
Research documentation example
If a record lists C1 as 10 mg/mL, C2 as 2 mg/mL, and V2 as 5 mL, then V1 is (2 × 5) ÷ 10 = 1 mL.
Common documentation mistakes
- Mixing concentration units between C1 and C2.
- Recording final volume without the starting volume calculation.
- Rounding before the final calculation is recorded.
