How do you find the relative molar mass with the fraction abundance and isotope molar mass?
To find the relative molar mass of an element using its isotopes, you multiply the molar mass of each isotope by its fractional abundance (the proportion of that isotope relative to the total). Then, you sum these products for all isotopes. The formula can be expressed as:
[ \text{Relative Molar Mass} = \sum (\text{Isotope Molar Mass} \times \text{Fractional Abundance}) ]
This gives you the weighted average molar mass of the element based on its isotopic composition.
What else can I help you with?
Calculate the atomic mass of an element?
By taking the wieghted averages of naturally occurring isotopes of that element. :)
Part of the atom that contains protons and neutrons is called?
Surely it's just a nucleus, as every version of an element is an isotope in its own right, and the atomic and molar masses are just an average made by relative abundance...hope this helps.
WHAT is the average mass of the isotopes of an element found in nature?
The average mass of the isotopes of an element found in nature is calculated based on the abundance of each isotope and its mass. This calculation takes into consideration the percentage abundance of each isotope in nature to determine the average atomic mass of the element.
What is the molecular formula of relative mass of 72?
There are many compounds with a relative mass of 72.Eg. pentane (C5H12), methyl butane (CH3)-(C4H9), dimethyl propane (CH3)2-(C3H6). Inorganic formula's can not easily be guessed, but undoubtly be found.Only one (isotope of an) element has the relative mass of 72: Gallium, (Ga-72), but this is not a natural, stable isotope. Gallium has not a molecular formula (being a metal like aluminum) only an atomic symbol: Ga.
What is the mass of a mole of isotope carbon-12?
According to the definition by IUPAC, the mass of a mold of carbon-12 isotope is exactly 12.0000 g.

What is the difference in molar mass and atomic mass?
molar mass is the actual mass of the one atom but relative mass is the average isotopes of the atoms.------------------------------------------Atomic mass is the mass of an isotope, expressed in atomic mass units.Molar mass is the mass of molecule, calculated from the atomic weights of the contained chemical atoms, expressed in grams.

What is the relationship between mole fraction and mass fraction in a given mixture?
The relationship between mole fraction and mass fraction in a mixture is that the mole fraction of a component is equal to its mass fraction divided by its molar mass, multiplied by the total mass of the mixture. This relationship helps in understanding the proportion of each component in the mixture based on their masses and molar masses.
How do you calculate molar mass?
You multiply the molar mass of the component element by how many of that atom appear in one molecule. You add all the elements' masses together to get the molar mass of the molecule. For example, SO2 1 * mass of sulfur =32.1 g 2 * mass of oxygen =32.0 g 32.1 g + 32.0 g = 64.1 g
Why can I use percent composition?
Percent composition is a useful tool in chemistry because it gives you insight into the relative abundance of elements in a compound. By knowing the percent composition, you can predict the physical and chemical properties of the compound and use it to calculate other information, such as molar mass or stoichiometry in reactions.
Why are molar masses not a whole number?
Molar masses are not whole numbers because they are calculated based on the average mass of isotopes present in a sample, taking into account the abundance of each isotope. Isotopes are elements with the same number of protons but different numbers of neutrons, leading to fractional atomic masses and consequently non-whole molar masses.
What is the mass of a mole of isotope carbon-12?
According to the definition by IUPAC, the mass of a mold of carbon-12 isotope is exactly 12.0000 g.
8. On most periodic tables a single atomic mass is listed instead of the mass numbers for all the stable isotopes. How is this mass related to the different isotopes?
In a normal periodic table, the molar mass of a given element, is made up of multiplying the mass of a given isotope of that element, with the abundance of that given isotope in percent. For example, Say for the element X, you know that it has two isotopes, X12 and X13. X12 has a molar mass of 12 g/mol, and you know that of all the X molecules in the world, X12 is found 95% of the time, X13 has a molar mass of 13g/mol, yet its abundence is only 5%. Therefore average molar mass for element X is calculated as such, (12 * .95)+(13*.05) = 12.05 g/mol. hope that helps.
