How do you calculate the atomic mass of an element with different isotopes?
To calculate average atomic mass from different isotopes of an element, we take into account the relative atomic masses of isotopes and their relative abundance on Earth. The following formula is used to calculate the needful : atomic mass = mass of isotope x percent abundance + mass of isotope x percent abundance / 100 (whole expression divided by 100)
How much effect do high percent abundance isotopes have on the average atomic mass of an element?
This entirely depends on the percentage of the different isotopes present. This is typically determined through mass spectrometry. After the percentages of the different isotopes are known, one times the percentage of each isotope by its relative atomic mass, then add this all together. After dividing this by 100, you will have attained the average atomic mass of a naturally ocurring element.
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)
What genetic material make up 3.2 percent of the body's mass?
3.2% Nitrogen Nitrogen is very common in proteins and organic compounds. It is also present in the lungs due to its abundance in the atmosphere.
How does the atomic mass of carbon show that it is an isotopes?
If your asking "how does the mass show there are isotopes", then the answer is this: Isotopes are found by using a mass spectrometer, and the abundance (percent amount) of each isotope is determined. Using this percent of abundance, the AVERAGE mass is reported on the periodic table. For example, if carbon 12 had mass of 12 and carbon 13 had mass of 13, but the percent abundance of 12 was 99% and the abundance of 13 was 1%, then the atomac mass would be 12*.99+13*.01=12.01 You can tell it has isotopes by seeing that the mass is a decimal and not a whole number. It is harder to tell with carbon, because it's only off by .01, but looking at chlorine it is more clear. Most isotope weights are very close to being whole numbers, like Cl35 mass is 34.98 and Cl37 is 36.97. But looking at Cl atomic weight, it is 35.45; the .45 tells you it is a average because the value lies between the whole numbers as a decimal. Cl is 35.45, which is an average of 35 and 37 that's 76% and 24% abundance respectively.
What is the difference between percent abundance and relative abundance?
"Percent abundance" and "relative abundance" are terms commonly used in the context of chemistry, particularly in relation to isotopes and the composition of elements. While they are often used interchangeably, there can be a subtle distinction between the two terms, depending on the context. Percent Abundance: Percent abundance refers to the proportion or percentage of a specific isotope within a sample of an element. It is calculated by dividing the number of atoms of a particular isotope by the total number of atoms of that element in the sample and then multiplying by 100. Percent abundance is a measure of how much of a particular isotope is present compared to the other isotopes of the same element. It provides information about the distribution of isotopes in a sample. Relative Abundance: Relative abundance also refers to the proportion of a specific isotope within a sample of an element. However, the term "relative" implies a comparison with other isotopes rather than expressing the value as a percentage. Relative abundance is often used when discussing isotopic ratios without converting them into percentages. It's more of a ratio or fraction that describes the ratio of the amount of one isotope to the total amount of all isotopes of the same element in a sample. In summary, while the terms are often used interchangeably and refer to the same basic conceptโthe proportion of a particular isotope in a sampleโpercent abundance" specifically conveys this proportion as a percentage, whereas "relative abundance" focuses on the ratio or fraction without necessarily converting it into a percentage. The choice of term might depend on the context of the discussion and the preferences of the speaker or writer.

What is is the result when you total the individual relative abundance?
the result is 1.00, because relative abundance is just the percent abundance in decimal form. The percent abundance sum is 100%, therefore the answer is 1.00 because the decimal of 100% is 1.00
How do you calculate the atomic mass of an element with different isotopes?
To calculate average atomic mass from different isotopes of an element, we take into account the relative atomic masses of isotopes and their relative abundance on Earth. The following formula is used to calculate the needful : atomic mass = mass of isotope x percent abundance + mass of isotope x percent abundance / 100 (whole expression divided by 100)
How do you calculate the fractional abundance of Cl-37?
The fractional abundance is calculated by dividing the abundance of the isotope of interest by the abundance of all the isotopes of the element. For chlorine-37, the percent abundance is 0.2434, or 24.34%.
What is the result when you total the individual percent abundance of isotopes of a given element?
How do you calculate percent abundance of an isotope?You find the isotope number and then you calculate that into a fraction and then turn the fraction into a percentage and divide it by the atomic number then times it by the mass and turn that answer into a percent and voila, there you have it.
How much effect do high percent abundance isotopes have on the average atomic mass of an element?

Sodium is considered a monoisotopic chemical element - sodium-23; the isotopes sodium-22 and sodium-24 exist only in ultrtraces.
What are the percent natural abundances of the two isotopes Ru-85 and Ru-87?
Their percent natural abundances are Ru-85 (72. 2 percent) and Ru-87 (27. 8 percent). Ru-85 and Ru-87 are the only naturally occurring isotopes of Rubidium out of its 35 known isotopes.

If an element has 3 isotopes with known masses what other information is needed to find the average atomic mass of the element?
You would also need to know the abundance of each of the isotopes, i.e., how much percent of each you will typically encounter.
