Milliequivalent weight
WebThe milliequivalent weight of a substance is one thousandth of its atomic weight. Since the equivalent weight of hydrogen is about 1 gm., the term milliequivalent (meq) may be defined as 1 milligram of hydrogen. It indicates that other ions also may be expressed in terms of milliequivalents. Consider calcium, for example. http://www.druginformation.com/calcs/mg,%20mEq%20and%20mmol/mg,%20mEq,%20and%20mM%20Conversion%20Calculator.php

You must also …
WebFormula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. These relative weights computed from the chemical equation are sometimes called equation weights. If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. In chemistry, equivalent weight (also known as gram equivalent ) is the mass of one equivalent, that is the mass of a given substance which will combine with or displace a fixed quantity of another substance. The equivalent weight of an element is the mass which combines with or displaces 1.008 gram of hydrogen or 8.0 grams of oxygen or 35.5 grams of chlorine. These values correspond to the atomic weight divided by the usual valence; for oxygen as example that is 16.0 …
