WebNov 30, 2024 · 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 g / 2 = 8.0 g. WebIt can be mathematically represented as. Equivalent weight = Molar Mass number of equivalents . The number of equivalents implies the charge carried by the compound. For example: For Ca ( OH) 2, the number of equivalents is 2 as the charge on Ca is 2+ and 2 equivalents of ( OH -) is present. The molecular formula of calcium hydroxide is = Ca (OH)2.

WebApr 1, 2016 · Equivalent mass may be defined as the number of parts by mass of a substance which combines with or displaces directly or indirectly 1.008 parts by mass of hydrogen or 8 parts by mass of oxygen or 35.5 parts by mass of chlorine. Why isn't it defined like "that mass of a substance which combines/displaces 1 gram of hydrogen" 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 … See more The first equivalent weights were published for acids and bases by Carl Friedrich Wenzel in 1777. A larger set of tables was prepared, possibly independently, by Jeremias Benjamin Richter, … See more When choosing primary standards in analytical chemistry, compounds with higher equivalent weights are generally more desirable … See more In polymer chemistry, the equivalent weight of a reactive polymer is the mass of polymer which has one equivalent of reactivity (often, the mass of polymer which corresponds to one mole of reactive side-chain groups). It is widely used to indicate the … See more The use of equivalent weights in general chemistry has largely been superseded by the use of molar masses. Equivalent weights may be calculated from molar masses if the … See more The term “equivalent weight” had a distinct sense in gravimetric analysis: it was the mass of precipitate which corresponds to one gram of See more WebJun 27, 2014 · Given that approximately 16 grams of oxygen contains a mole of oxygen atoms, the weight of an oxygen atom in grams can be solved by dividing by Avogadro's number. 16/(6.02 x 10^23) is equal to ... shanks restaurant
