Concentration Calculation: mg per ml/IU

In the context of scientific research, it is essential to understand the correct calculation of a substance's concentration after dilution. Concentration is expressed in milligrams per milliliter (mg/ml) and results from a simple mathematical relationship between the total amount of substance (mg) and the total volume of solvent used (ml).

Base Calculation Formula

Concentration (mg/ml) = Total amount (mg) ÷ Total volume (ml)

This calculation allows for precise determination of the final concentration of a solution prepared for laboratory or research purposes.

Examples of Concentration Calculation

Peptide with 5 mg

5 mg in 2 ml → 2.5 mg/ml → 2.5 mg/100 IU
5 mg in 3 ml → 1.67 mg/ml → 1.67 mg/100 IU
5 mg in 4 ml → 1.25 mg/ml → 1.25 mg/100 IU

Peptide with 10 mg

10 mg in 2 ml → 5 mg/ml → 5 mg/100 IU
10 mg in 3 ml → 3.33 mg/ml → 3.33 mg/100 IU
10 mg in 4 ml → 2.5 mg/ml → 2.5 mg/100 IU

Peptide with 40 mg

40 mg in 2 ml → 20 mg/ml → 20 mg/100 IU
40 mg in 3 ml → 13.33 mg/ml → 13.33 mg/100 IU
40 mg in 4 ml → 10 mg/ml → 10 mg/100 IU

Peptide with 50 mg

50 mg in 2 ml → 25 mg/ml → 25 mg/100 IU
50 mg in 3 ml → 16.67 mg/ml → 16.67 mg/100 IU
50 mg in 4 ml → 12.5 mg/ml → 12.5 mg/100 IU
