WebMolar mass is defined as the mass of one mole of a substance under standard conditions. It is denoted by a lower case m and is commonly expressed in g/mol (grams per mole). In theory, the molar mass is the sum of the masses of all the individual atoms, ions, or molecules in a molecule or chemical formula. However, in reality, it is more complex ... WebAverage atomic mass is the average mass of the compounds present in it. Average atomic mass = f 1 M 1 + f 2 M 2 + … + f n M n. Here, f represents the relative abundance of the isotope and M is the atomic mass of the isotope. It is used because its numerical value is equal to the element's molar mass. Suggest Corrections.
