The average Atomic Mass is [26.91(0.6933) + 28.99(0.3067)] = 27.55, to the justified number of significant digits.

What is the result when you total the individual percent abundance of isotopes of a given element?
How do you calculate percent abundance of an isotope?You find the isotope number and then you calculate that into a fraction and then turn the fraction into a percentage and divide it by the atomic number then times it by the mass and turn that answer into a percent and voila, there you have it.
Which value of an element is calculated using both the mass and relative abundance of each of the naturally occurring isotopes of this element?
The atomic weight.
Not naturally occurring?
Something that is not naturally occurring is man made.
When masses of all naturally occurring isotopes of a particular element are averaged the result is called the elements?
When the mathematical products of the mass of each naturally occurring isotope of a particular element, each mass being multiplied by the natural abundance fraction* of the particular isotope, are added, the result is called the element's atomic weight or, if the masses are expressed in grams per Avogadro's Number of atoms, the gram atomic mass._____________________________*The abundance fraction equals exactly 0.01 times the percent abundance of the isotope.
Is phosphorus a naturally occurring or man made?
Phosphorus is naturally occurring. It is found in rocks
How do you calculate the average mass of a naturally occurring element?
By multiplying the mass number of each naturally occurring isotope of the element by the fractional abundance of the same isotope, then adding all the resulting products.
When the masses of all naturally occurring isotopes of a particular element are averaged the result is called the elements?
Atomic weight, if the average is taken by weighting the mass of each naturally occurring isotope by its natural abundance.
How do you find the abundance of a naturally occurring element?
Attentively analyzing hundreds and hundreds of samples of rocks, minerals, soils, waters.

How do you calculate percent abundance of an isotope?You find the isotope number and then you calculate that into a fraction and then turn the fraction into a percentage and divide it by the atomic number then times it by the mass and turn that answer into a percent and voila, there you have it.
What is fractional abundance?
atomic weight are average atomic masses, the sum of the mass of each naturally occurring isotope of an element times its fractional abundance. OR All elements exist as isotopes in nature. This means that carbon has 6 protons, but some varieties have 6 neutrons and some may have 8. This would be denoted as carbon - 12 and carbon -14 A fractional abundance simply means, what is the mixture of these isotopes in nature. or the carbon example above, approx. 99% is the carbon -12 variety and less than 1 % is carbon-14. When they are averaged together, based on this relative presence in nature, you get an average atomic mass of 12.011
