Formula Used
The equivalent weight ($EW$) calculation relies on the fundamental relationship between the molecular weight of a substance and its valence factor ($n$). The core expression is:
$$EW = \frac{M}{n \times g}$$
Where $M$ is the molar mass, $n$ represents the valency or electron/proton exchange capacity, and $g$ represents the count of active functional groups.
