Equivalent mass/weight

Equivalent The amount of a substance that will react with one mole of H+ or OH-. The related term equivalent mass ( weight ) refers to a molar mass of a substance divided by the absolute value of its valence state. For anion exchange capacity and cation exchange capacity measurements, the results are usually reported in milliequivalents (1/1000 of an equivalent) per 100 g of material. 

As a result of this possible confusion, the concept of equivalent mass (weight) is rarely used. 

Mass the quantity of matter in a body. Equivalent to weight in a region with constant gravitational acceleration. 

Epoxidation catalysts, organic titanium compounds as, 25 135 Epoxide determinations, 10 385 Epoxide equivalent mass (EEM), 10 355 Epoxide equivalent weight (EEW), 10 355, 361-363, 385... 

A complementary approach to the parabolic barrier problem is obtained by considering the Hamiltonian equivalent representation of the GLE. If the potential is parabolic, then the Hamiltonian may be diagonalized" using a normal mode transformation. One rewrites the Hamiltonian using mass weighted coordinates q Vmd. An orthogonal transformation matrix... 

D.E, 20 this was a maltodextrin that had a glycemic index (dextrose equivalent) rating of 20. Cheaper than food, easier to consume, excellent absorption, and goes well in protein shakes during any mass weight gain protocol. 

Equivalence and normality are outdated terms, although you may come across them in older texts. The magnitude of an equivalent mass (equivalent weight) can be simply identified from the balanced equation for the reaction being considered. Remember that the equivalent mass can change, depending on the reaction, as the following reactions illustrate. 

A milligram equivalent of a substance is its equivalent weight expressed in milligrams. The equivalent mass of H2SO4 is 49.04 g therefore Img equivalent of H2SO4 =... 

The laboratory unit used to define polymer retention, Cp, is in mass of polymer per unit mass of solid, usually in micrograms per gram of rock (itg/g). Sometimes (e.g., in UTCHEM), the unit is in grams per 100 milliliter (cm ) of pore volume (PV), g/100 mL PV, which is equivalent to weight percent (wt.%) if the solvent (water) density is 1 g/mL and the pore volume is filled up by the solvent (water) only. In bulk static adsorption, a more fundamental measure of adsorption is the mass of polymer per unit surface area of solid, which is referred to as the surface excess, Cps, usually in milligrams or micrograms per square meter (mg/m or (tg/m ). Sometimes, in field applications, the retention unit is in mass of polymer per unit volume of rock, usually in lb/ acre-foot.
