How does the average atomic mass of an element differ from the mass of an individual atom of the same element?
The masses and relative abundances of all naturally occurring isotopes of the element are required to calculate average atomic mass of the element.
What characteristic of an element is the average mass of it's isotopes?
The atomic weight of an element is a number that takes into account the natural distribution of the isotopes of that element.
What data must you know about the the isotopes of an element to calculate the atomic mass of an element?
Number of protons
How the atomic mass of an element is affected by the distribution of its isotopes in nature?
The atomic mass of an element is the average of its isotopes, weighted by abundance in nature.
The atomic mass of an element is defined as the weighted average mass of that element's?
For the chemical elements the correct expression is atomic weight.This value is the weighted average mass of the natural isotopes of this element.
What information about an element's isotopes is needed to calculate that element's average atomic mass?
the atomic number of each isotope-apex;)
How do you calculate the atomic mass of an element containing a mixtures of isotopes?
weighted average of the various iisotopes
How does the average atomic mass of an element differ from the mass of an individual atom of the same element?

How is the atomic mass of an element calculate?
By taking the wieghted averages of naturally occurring isotopes of that element. :)
What is the average mass of the mixture of an elements isotopes?
All of the isotopes in an element's atomic masses divided by the amount of isotopes there are is the weighted-average mass of the mixture of an elements isotopes.
Which is the average of the mass numbers of an element's isotopes?
the Atomic Mass
