What are the formulas behind the Concentration Calculator?
Reading time: 1minDiluent calculation
- [Diluent amount] = [Final Volume] - SUM[Volume of all ingredients]
Ingredient amount calculation
All liquid ingredients (except the unit %(w/v))
- [Ingredient amount] = [Final concentration] * [Final Volume] / [Initial concentration]
Liquid ingredients, unit %(w/v)*
- [Ingredient amount] = [Final concentration] * [Final Volume] / 100
* This formula is used when you want to measure a liquid ingredient by weight, for example in the case of very viscous components like concentrated glycerol or tween20.
Solid ingredients, molar concentration.
- [Ingredient amount] = [MW] * [Final concentration] * [Final Volume]
Solid ingredients, w/v concentration
- [Ingredient amount] = [Final concentration] * [Final Volume]
Solid ingredients, % (s) concentration
- [Ingredient amount] = [Final concentration] * [Final Volume] / 100
