In the other tutorial, the average atomic weight is the unknown value calculated.
In this tutorial, the unknown values calculated are the TWO percent abundances.

Jan 30, 2012 ... If you're given the mass of each isotope of an element, and the average atomic
mass, you can calculate the percent (%) abundance of each ...
In this case, you want to find the percentage of the lighter isotope, so the "x" is
associated with 106.90509. Since the sum of the isotopic abundance
Percent abundance can be calculated by finding the percentage of an isotope
compared to another isotope of an element using its relative atomic mass. This is
... + (1-x)(c) = a and the unknown abundance is the "x.". "B" refers to the first
isotope's atomic mass and "c" refers to the second... ... What is percent
Percent abundance describes the prevalence of each of an element's isotopes in
nature. The percent abundance of each isotope is used in the calculation of an ...
Atomic Mass Calculations from Percent Abundance ... Example 1 The natural
abundance for boron isotopes is: 19.9% <sup>10</sup>B (10.013 amu) and 80.1% <sup>11</sup>B ...
An isotope of an element is a variant in the nuclear makeup of the atom. Isotopes
have different numbers of neutrons from atom to atom of the same element.
It is the obtained by calculating percent abundance of each isotope and their
atomic mass ... For finding the average atomic mass of an element it is necessary
Nov 11, 2015 ... sum("isotope mass")*("percent abundance") For example, suppose we want to
find the percent abundance of chlorine isotopes ""^35Cl and ...
