Stock Solution Formulation Calculator


The Stock Solution Formulation Calculator determines the amount of an additive required to yield a stock solution with a given volume and concentration.

Input Field Definitions

Target Concentration – The desired concentration of the additive in the stock solution.

Solution Volume – The volume of the stock solution being made.

Output Field Definitions

Mass of Additive Required – The mass of the additive required to yield the desired concentration of the additive in the specified volume of stock solution.

Calculation Details

Concentration is mass per unit volume. So, the required mass is simply the desired volume multiplied by the desired concentration, or:

ma = vscs


ma = mass of additive, kg

vs = solution volume, liters

cs = concentration of substance in solution, kg/L
