Feb 7, 2020 · Learn the definition and formula of milliequivalent (mEq), a unit of concentration based on the number of ions in solution. See examples of how to calculate mEq for different substances and solutions.
A milliequivalent is a measurement reflecting the amount of substance in terms of its chemical activity or ionic concentration. It is particularly useful for calculating concentrations of electrolytes in a solution and balancing chemical equations.
By this definition, the number of equivalents of a given ion in a solution is equal to the number of moles of that ion multiplied by its valence. For example, consider a solution of 1 mole of NaCl and 1 mole of CaCl2. The solution has 1 mole or 1 equiv Na+, 1 mole or 2 equiv Ca2+, and 3 mole or 3 equiv Cl−.
Nov 23, 2022 · Milliequivalents and Millimoles Calculation. November 23, 2022 0. The quantities of electrolytes administered to patients are usually expressed in terms of mEq. Weight units such as mg or g are not often used for electrolytes because the electrical properties of ions are best expressed as mEq.
Nov 30, 2023 · Learn how to calculate milligrams of a substance given the milliequivalents, molecular weight and valence. Use the online calculator to convert meq to mg for various substances in medical and nutritional contexts.
This video demonstrates key steps in performing milliequivalents calculations and provides pertinent examples.
Jul 4, 2023 · Learn how to calculate milliequivalents (mEq) of electrolytes using the formula and an example problem. Use the online calculator to enter the weight, molecular weight and valence of a substance and get the mEq answer.
