Equivalent weight is equal to which of the following calculations?

The concept of equivalent weight is important in chemistry, particularly in the context of reactions and stoichiometry. The equivalent weight of a substance is defined as the mass of that substance that will combine with or displace 1 mole of hydrogen atoms or 1 mole of electrons in a reaction.

The correct calculation for equivalent weight is derived from dividing the molecular weight by the valence. Valence refers to the number of moles of hydrogen ions that can be displaced or combined by one mole of the substance. By dividing the molecular weight (the mass of one mole of the substance) by its valence (which reflects how many moles of reactive species one mole of the substance can affect), we obtain the equivalent weight.

This calculation is straightforward: when you have a substance with a defined molecular weight, dividing it by the valence tells you how many grams correspond to its equivalent weight. By knowing the equivalent weight, pharmacists and chemists can accurately determine dosages and effects in pharmacology and chemistry.

Other options involve incorrect relationships or additional multiplicative factors that are not part of the standard definition of equivalent weight. The fundamental relationship that defines equivalent weight is simply molecular weight divided by valence. Understanding this will help with calculations in various applications involving equivalent
