Europium has a mass of 150.9196amu and a mass of m152.9209amu the average atomic mass of Eu is 151.96amu calculate the relative abundance of the two europium isotopes?
Europium 150.9196 has relative abundance of 51.99%, while Europium 152.9209 has a relative abundance of 48.04% (Assuming that these are the only 2 isotopes of Europium
What information is necessary to determine the atomic mass of the element chlorine?
The atomic mass and the relative abundance of each naturally occurring isotope of chlorine.
How do you calculate the average relative atomic mass of neon?
To calculate the relative atomic mass of an element (which is by its definition an average), you need the mass number and relative abundance of each isotope present. Suppose we have the following data from the mass spectrometer: first isotope mn X, abundance A% second isotope mn Y, abundance B% third isotope mn Z, abundance C%. Then ram = (A/100 x X) + (B/100 x Y) + (C/100 x Z) If there are more than 3 isotopes, just do the same for each one and add all the expressions together.
How do you calculate the average atomic mass of a element?
The mass of the isotope multiplied by its relative abundance plus the the mass times abundance of other isotopes.(mass of isotope)(relative abundance) + (mass of isotope)(relative abundance) = average atomic massExample: Carbon can be naturally found as carbon- 12 or carbon- 13. The mass of carbon- 12 is 12 amu and it makes up 98.93% of naturally found carbon. The mass of carbon- 13 is 13.00335 amu, and it makes up 1.07% of naturally found carbon. So the equation to calculate the average atomic mass of carbon is:(0.9893)(12 amu) + (0.0107)(13.00335 amu) = 12.01 amu
How does stability of an isotope relate to its abundance in nature?
The stability of an isotope relate to its abundance in nature by the hemoglobin anatomy by turning into a sharknado at the tempature of the following atoms.

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 does the relative atomic mass of an element tell us about the relative abundance of an isotope?
None. The relative abundance of isotopes is used to calculate the Average Mass (by multiplying the Atomic Mass of the isotopes by their relative abundancies and adding the products together) while the Atomic Mass is simply the number of protons plus the number of neutrons.
What is the name of the instrument used to measure the relative abundance of an isotope?
This would be done in a mass spectrometer.
How is the atomic mass for chlorine related to isotopes for that atom?
The average atomic mass is weighted by the most common isotopes and their relative abundance.
How does a mass spectrograph show the relative abundance of isotopes of elements?
in modern instrument,each ion strikes a detector,ionic current is amplified and is fed to the recorder. The recorder makes a graph showing the relative abundance
What information is necessary to determine the atomic mass of the element chlorine?
The atomic mass and the relative abundance of each naturally occurring isotope of chlorine.

Which value of an element is calculated using both the mass and relative abundance of each of the naturally occurring isotopes of this element?
The atomic weight.
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
Does copper have an element?
Copper is a metallic element. It is located in the d-block of the periodic table. Its relative atomic mass is 63.5 (relative abundance of two isotopes 63 and 65).
How do you calculate the average atomic mass of a element?
The mass of the isotope multiplied by its relative abundance plus the the mass times abundance of other isotopes.(mass of isotope)(relative abundance) + (mass of isotope)(relative abundance) = average atomic massExample: Carbon can be naturally found as carbon- 12 or carbon- 13. The mass of carbon- 12 is 12 amu and it makes up 98.93% of naturally found carbon. The mass of carbon- 13 is 13.00335 amu, and it makes up 1.07% of naturally found carbon. So the equation to calculate the average atomic mass of carbon is:(0.9893)(12 amu) + (0.0107)(13.00335 amu) = 12.01 amu
