What is meant by gram equivalent weight?
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. 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.
How do you calculate equivalent current?
The sum of the current in each individual branch is equal to the current outside the branches. The equivalent or overall resistance of the collection of resistors is given by the equation 1/Req = 1/R1 + 1/R2 + 1/R3 …
What is the equivalent weight of iron?
Iron (atomic weight 55.845) has an equivalent weight of 27.9225 in ferrous compounds (valence 2) and 18.615 in ferric compounds (valence 3).
What is the formula of equivalent weight?
Equivalent Weight 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 is calculated using equivalent_weight = Molecular Weight / N Factor. To calculate Equivalent Weight, you need Molecular Weight (Mw) and N Factor (nf).
How do you calculate equivalent mass?
There are two formulas that may be used to calculate mass: mass is equal to the volume of an object multiplied by its density (m=v*d) and mass is equivalent to an object’s weight divided by the acceleration of gravity (m=w/g). The appropriate formula depends on the available variables.
How much should I weigh calculator?
The Mifflin St. Jeor formula is the most accurate formula you can use to find your ideal weight. You need to know your height, weight and you can find your ideal body weight. Here you go: wt in pounds = m2 x ht (in inches) x 14.14 + m2 / 4. Let’s say you’re 5 feet, 8 inches tall, and you want to know how much you should weigh.
What is equivalent weight in chemistry?
equivalent weight. n. The weight of a substance that will combine with or replace one mole of hydrogen or one-half mole of oxygen. The equivalent weight is equal to the atomic weight divided by the valence. n. (Chemistry) the weight of an element or compound that will combine with or displace 8 grams of oxygen or 1.007 97 grams of hydrogen.
