How to Find the Average Isotopic Mass Using Percent Abundance and...
Each individual atom within an element has a specific mass. Yet the individual atoms vary in mass, depending on how many protons they have. Most lithium atoms, for example, contain four protons, lending them a relative mass of 7. A small pe... Read More »

How to Find Fractional Abundance of an Isotope
Isotopes of a particular element are atoms that contain the same number of protons and electrons but have a different number of neutrons. Due to the added neutrons, these atoms have a different atomic mass. This variation in mass, however, ... Read More »

How to Find the Relative Abundance of Isotopes
Most elements come in multiple isotopes, atoms that have the same number of protons and electrons but different number of neutrons. Different isotopes react the same chemically, but their atomic weights are different; the atomic weights giv... Read More »

total mass = 105.92 this is the weighted average of the 3 isotopes X(104.93) + Y(105.22) + Z(107.29) = 105.92 we also know that the abundance of each isotope must = 1 X + Y + Z = 1 you are missing information in this question. we need at le...

If you know the element, look up the atomic mass on the periodic table. It's the number with places after the decimal. If there are only two isotopes they have to add up to 100% (or in decimal form 1) so you set it up like this: (atomic wei...
