You must specify the element whose isotopes you want the weighted average mass for.
Otherwise there is no answer as just averaging the masses of isotopes without accounting for how much of each isotope is present in a sample of an element is meaningless. Also averaging masses of isotopes of different elements is also meaningless.
What else can I help you with?
What is the average atomic mass of an element is the average atomic masses of what kind of isotopes?
average atomic massof an element=(Atomic mass of first isotope X % of that isotope) + (Atomic mass of second isotope X % of the second isotope)
What is the average mass of the isotope of an element?
the average mass numbers of the isotopes of an element
Which is a factor in determining the average atomic mass of an element?
The two main factors in determining the average atomic mass of an element are:the isotopic composition of the element (the fraction of each isotope)the atomic mass of each isotope
Which atom has an average mass not equal to its common isotope?
Hydrogen atom has an average mass not equal to its common isotope. The most common isotope of hydrogen, hydrogen-1, does not have a neutron in its nucleus, while the average mass of a hydrogen atom accounts for the other isotopes of hydrogen which do contain neutrons.
Why is each isotope's mass multiplied by the isotope's percent abundance?
Each isotope's mass is multiplied by its percent abundance to account for the contribution of each isotope to the overall average atomic mass of an element. This calculation ensures that the final average atomic mass reflects the weighted average of the masses of all isotopes based on their abundance in nature.
The mass of the mixture of the isotopes for an element?
The mass of a mixture of isotopes for an element is a weighted average of the masses of each isotope, calculated based on the isotope abundances. The formula for calculating the average atomic mass is: (mass of isotope 1 x abundance of isotope 1) + (mass of isotope 2 x abundance of isotope 2) + ...
If an element has three isotopes with known natural abundance percentages what other information is needed to find the average atomic mass of the element?
The abundance percentage of each isotope
Average atomic mass is closest to its most?
The average atomic mass of an element is closest to the mass number of the most abundant isotope of that element. This is because the average atomic mass takes into account the relative abundance of each isotope when calculating the overall mass.
Calculate the average atomic mass of an unknown element that has two naturally-occurring isotopes The first isotope occurs 75.47 percent of the time and has a mass of 248.7 amu The second isotope occu?
To calculate the average atomic mass, multiply the mass of each isotope by its natural abundance (expressed as a decimal), then add the results together. For the unknown element: Average atomic mass = (0.7547 * 248.7 amu) + (0.2453 * x) Given the only known isotope mass is 248.7 amu, you'll have to provide the mass of the second isotope to determine the average atomic mass.
What are the steps in the process of calculating average in atomic mass given data about the isotopes of an element?
To calculate the average atomic mass of an element, you need to multiply the mass of each isotope by its abundance (as a decimal), then sum these values for all isotopes of that element. This will give you the weighted average atomic mass. The formula is: average atomic mass = (mass isotope 1 x abundance 1) + (mass isotope 2 x abundance 2) + ...
If an element has three isotopes with known masses what information is needed to find the average atomic mass of the element?
You would need to know the abundance of each isotope to find the average atomic mass of the element. The average atomic mass is calculated by multiplying the mass of each isotope by its relative abundance and then summing these values together.
How is the mass number of an isotope different from the average atomic mass that is on the periodic table?
The mass number for a particular isotope of an element is a precise value. The average atomic mass for an element is the value you would measure for that element given all the isotopes it has and their abundance in the sample.
