Theoretical equivalent 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 … Visa mer 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, … Visa mer When choosing primary standards in analytical chemistry, compounds with higher equivalent weights are generally more desirable … Visa mer In polymer chemistry, the equivalent weight of a reactive polymer is the mass of polymer which has one equivalent of reactivity (often, the … Visa mer The use of equivalent weights in general chemistry has largely been superseded by the use of molar masses.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 chemistry of the substance is well known: • Visa mer The term “equivalent weight” had a distinct sense in gravimetric analysis: it was the mass of precipitate which corresponds to one gram of analyte (the species of interest).

WebbIn order to perform the calculation, all we have to do is to multiply the weight (kg), the metabolic equivalent of a task (MET) and the time of the activity (hr). Remember that 1 MET = 1 kcal/kg/hr Units of time must be converted to hours. Therefore, 30 min = 0.5 hr Calories burned = 70 kg x 3 kcal/kg/hr x 0.5 hr = 105 kcals burned
