Does equivalent weight have any units?
In physical chemistry we do not use any unit to measure the equivalent weight of any atom or molecule. Equivalent weight simply refers to the amount of any chemical substance. If it is measured in grams, that equivalent weight is called gram equivalent weight.
What is equivalent weight measured in?
The equivalent weight of an element or radical is equal to its atomic weight or formula weight divided by the valence it assumes in compounds. The unit of equivalent weight is the atomic mass unit; the amount of a substance in grams numerically equal to the equivalent weight is called a gram equivalent.
What is the difference between gram equivalent and equivalent weight?
The key difference between gram equivalent and equivalent weight is that gram equivalent describes that the mass of one equivalent is given in the unit of gram whereas equivalent weight describes the mass of one equivalent in any unit of measurement.
What is the difference between molecular weight and equivalent weight?
The key difference between gram molecular weight and gram equivalent weight is that the term gram molecular weight refers to the mass of a molecule in grams which is numerically equal to the molecular weight of that substance, whereas the term gram equivalent weight refers to the mass of one equivalent in grams.
What is the relation between equivalent weight and Valency?
The valency of elements in the same group in the periodic table is the same. The number of electrons in an element’s outer shell determines its valency. The equivalent weight of an element is its gram atomic weight divided by its valence (combining power).
What is the base unit for weight?
kilogram
The kilogram is the base unit of mass in the International System of Units (SI).
Is weight a unit?
The unit of measurement for weight is that of force, which in the International System of Units (SI) is the newton….
| Weight | |
|---|---|
| Common symbols | |
| SI unit | newton (N) |
| Other units | pound-force (lbf) |
| In SI base units | kg⋅m⋅s−2 |
What is the equivalent measurement?
In mathematics, and specifically in measure theory, equivalence is a notion of two measures being qualitatively similar. Specifically, the two measures agree on which events have measure zero.
Why is equivalent weight used?
equivalent weight, in chemistry, the quantity of a substance that exactly reacts with, or is equal to the combining value of, an arbitrarily fixed quantity of another substance in a particular reaction. The equivalent weight of an element is its gram atomic weight divided by its valence (combining power).
Is gram equivalent the same as no of equivalent?
Gram equivalent weight is equal to mass in grams numerically equal to Equivalent Weight. To calculate the Gram Equivalent Weight, we use the formula Eq = MW / n.
What is the relationship between equivalent weight and molecular weight?
For compounds that function as oxidizing or reducing agents (compounds that act as acceptors or donors of electrons), the equivalent weight is the gram molecular weight divided by the number of electrons lost or gained by each molecule—e.g., potassium permanganate (KMnO4) in acid solution, 158.038/5 g; potassium …
