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
