# Equivalent Weight Calculator

Equivalent Weight Calculator – a powerful tool designed for chemists, researchers, and students working with chemical reactions. The Equivalent Weight Calculator simplifies the process of determining the equivalent weight of a substance, a crucial step in stoichiometry and quantitative analysis.

### What is the Equivalent Weight Calculator?

The Equivalent Weight Calculator is a specialized tool that helps determine the equivalent weight of a substance in a chemical reaction. It streamlines calculations involved in stoichiometry, allowing users to make precise measurements and predictions during chemical experiments and analyses.

### What is the formula for calculating Equivalent Weight Calculator?

The calculator utilizes the following formula to determine the equivalent weight (EW)

`EW = M/n`

Where

• M : is the molecular weight or molar mass of the substance, and
• n : is the valence or the number of equivalents.

This formula is fundamental in understanding the reactivity and stoichiometry of substances in chemical reactions.

### Illustrated Examples:

Example 1

Molecular weight (M): 56 g/mol

Valence (n): 2

`EW = 56/2 =` 28 g/equiv

Example 2

Molecular weight (M): 120 g/mol

Valence (n): 3

`EW = 120/3 = ` 40 g/equiv

Example 3

Molecular weight (M): 90 g/mol

Valence (n): 1

`EW = 90/1 = ` 90 g/equiv
