Weighted average mass of the mixture of its isotopes?
The weighted average mass of a mixture of isotopes is calculated by multiplying the mass of each isotope by its natural abundance, and then summing these values together. This gives a more accurate representation of the overall mass of the isotopes in the mixture, taking into account their relative abundances.
Why is it important to use a weighted average when determining the average atomic mass of your element?
The majority of chemical elements have one or more natural isotopes; each isotope has a different mass and concentration. A weighted average atomic weight is unavoidable for a correct evaluation.Don't use the expression atomic maas - this in only for isotopes. For chemical elements IUPAC recommend atomic weight.
Why do elements which exists as isotopes have fractional atomic mass?
Each isotope of an element has a different Atomic Mass, so an average is taken of all the isotopes, but the average is weighted because the natural abundance (%) of each isotope is factored in. If hydrogen-1 is much more abundant than deuterium and tritium, then the weighted average will be closer to 1 than 2 or 3 but not a whole number. The following equation shows how percent abundance factors into the weighted average. (atomic mass A)(X% abundance) + (atomic mass B)(Y% abundance)...=(weighted average of all isotopes of the element)(100% abundance)
Is the atomic mass used for the mass of an element which has isotopes?
Yes, it must be used as all elements have one or more isotopes and all elements have an atomic mass.
What is the average atomic mass compared to atomic mass?
The average atomic mass is a weighted average of the masses of all isotopes of an element, taking into account their abundance. The atomic mass listed on the periodic table is the weighted average of all naturally occurring isotopes of the element. So, they are essentially the same thing, with the average atomic mass being a more specific term.

If 85 percent of a grade is 80 and the other 15 percent is 91 what is the final grade?
You have what's known as a weighted average. The 80 score is weighted more heavily than the 91 score, so the weighted average will be closer to 80 than a non-weighted average. 0.85 x 80 = 68 0.15 x 91 = 13.65 68 + 13.65 = 81.65

What is an isotope and why are atomic masses usually in decimal form?
An isotope is a variant of the atom with the same number of protons but more or fewer neutrons. The atomic mass is an average of the isotopes of the element. The average is weighted according to the relative abundance of such isotopes.
The relative abundance of each isotope of an element determines its?
The relative abundance of each isotope of an element is used to determine its atomic mass. This is the weighted average of all naturally occurring isotopes.
What is the weighted average mass of all the know isotopes for an element?
The weighted average mass of all the known isotopes of an element is calculated by taking the mass of each isotope, multiplying it by its natural abundance, and then summing up these values for all isotopes. This calculation takes into account the relative abundance of each isotope in nature to give a more accurate representation of the average mass of the element.
Where does the 0.5 in chlorine's atomic mass come from?
There are different isotopes of the element. Isotopes are atoms of an element that have different amounts of protons, so the isotopes with more protons weigh more because there is more mass in the atom. Some isotopes are more common than others, and the atomic mass is a weighted AVERAGE of all the isotopes of that element. On most elements there is a large difference between the most common and lesser common isotopes, but chlorine has 2 isotopes that are very close. So the average ends up between the two numbers. The actual weight of 1 atom will never be something.5 because protons and neutrons weigh 1amu and electrons weigh 0. But in most cases the sample of a chemical you use will be a mixture of the isotopes, so the .5 weight will be correct.
How often do women become engineers?
Because engineering is based in math and science, it historically has always been dominated by men. While this is slowly, slowly changing and more women are finding their way into the profession, it is still heavily weighted on the other side.
Do isotopes contain more electrons than other Atoms?
No, they contain different number of electrons. Isotopes differ in their number of neutrons.
