### How to Calculate Equivalent Weight Sciencing

The concept of equivalent weight allows you to explore the fact that atoms combine to form molecules in fixed number ratios, not mass ratios. That is, while element masses differ, when it comes to bonding with other atoms, the number of atoms, eed in moles, is the determining factor in how much of a given element or compound will react with a given mass of another. How to Calculate a Milliequivalent SciencingTo calculate a milliequivalent (mEq) you have to have two pieces of information:The mass of the substance in question and the molar mass (or molecular weight) of that substance. You must also be able to identify its valence from its molecular formula, as this determines ion number in solution.
