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 ... WebThe average atomic mass (sometimes called atomic weight) of an element is the weighted average mass of the atoms in a naturally occurring sample of the element. Average masses are generally expressed in unified atomic mass units (u), where 1 u is equal to exactly one-twelfth the mass of a neutral atom of carbon-12. Created by Sal Khan.
