Because all the atoms that make up an element have the same number of protons but sometimes differ in their number of neutrons, some of the atoms of the element will vary in mass. This results in the weighted average sometimes having fractions of an atomic mass unit. For example, fluorine...

For instance, Hydrogen is approximately 99% hydrogen with a mass number of 1 and 1% with a mass number of 2. The average mass is a weighted average. We weight the more prevalent isotope more heavily. In order to calculate the relative average atomic mass of an element we need to know ...

For example, there are 22.99 grams of sodium per mole of sodium, but there are 196.97 grams of gold per mole of gold. The grams per mole of an atom or molecule is its atomic mass or molecular mass respectively. The periodic table of the elements specifies the average atomic masses of ...
Is average a function or formula? Answer. It’s a function we run to get the average of a group of numbers using the formula of the average. ...Read full What are the difficulties of using a formula or a function? Answer. As the programmer is not the one doing every step of a ...
Formula Mass: In chemistry, the formula mass of a molecule or compound is always manifested in atomic mass units (amu). If we want to calculate the formula mass of any molecule or compound, we need to take the sum of the average atomic mass of all the atoms included in the empirical ...
