Field notes
The page explains the distinction between final volume and diluent volume: V2 is the total, so the amount of diluent is V2 − V1. It also notes that converting between molar and mass concentrations requires molecular weight, while percent values are treated as weight per volume only when paired with mass units. The calculator is presented as free and can be used without a visible sign-in gate.
