5 Questions
What is isotopic abundance?
Isotopic abundance refers to the relative amount of each isotope of an element in a given sample, expressed as a percentage.
How is the average atomic mass calculated?
The average atomic mass is calculated as a weighted average of all the isotope masses, taking into account their percent abundances.
What influences the average atomic mass in a weighted average calculation?
In a weighted average calculation, the isotope with the greatest % abundance has the biggest influence on the average atomic mass.
What information is needed to calculate the average atomic mass?
To calculate the average atomic mass, you need the number of isotopes, the masses of each isotope, and the % abundance of each isotope.
How does the average atomic mass differ from the mass of a specific isotope?
The average atomic mass is a weighted average of all the isotope masses for a particular element, taking into account their percent abundances, while the mass of a specific isotope is the mass of that particular isotope.
