Molecular weight
Molecular weight refers to the total mass of a molecule, which is the sum of the atomic masses of its constituent atoms. It is a fundamental concept in chemistry and biochemistry, and is used to characterize and identify molecules. The molecular weight of a molecule can be calculated using the atomic masses of its constituent atoms, which are typically listed in a periodic table. Molecular weight is an important factor in determining the physical properties and chemical properties of a molecule, such as its boiling point and solubility. It is also used in various fields, including pharmaceuticals, biotechnology, and materials science.
