Formula and method
50 mg in a final 10 mL volume has concentration 5 mg/mL.
Mass concentration = dissolved mass / final solution volume
Worked example
Enter these known values and leave the other values blank.
- Dose
- 50 mg
- Dose volume
- 10 mL
- Reconstitution concentration
- 5 mg/mL
Assumptions and limitations
- The volume means final solution volume, not necessarily the volume of solvent added. The model assumes complete dissolution and homogeneous concentration.
- This arithmetic does not determine a medication dose, preparation method, product stability or injectable compatibility. Follow the product-specific instructions when handling a formulated product.
Common questions
What does this model assume?
The volume means final solution volume, not necessarily the volume of solvent added. The model assumes complete dissolution and homogeneous concentration.
Can I solve backward?
Clear the unknown value and enter compatible known values. Choices, one-way outputs and singular boundary cases cannot always be inverted.
