This calculator calculates for the amounts of stock chemicals to use to adjust the composition of a batch
with five active ingredients. The amount of diluent (commonly water) to use is also calculated if needed
to lower the concentration of a ingredient or component. Ideally, the purer a stock chemical used for active
ingredient concentration adjustment is the better. This calculator can handle general cases where all five
components (plus diluent) can be present in a stock chemical.
