Final answer:
The average atomic mass of a mixture of isotopes is affected by the number of isotopes, isotopic masses, and the abundance of each isotope.
Step-by-step explanation:
In chemistry, the average atomic mass of a mixture of isotopes is affected by a combination of factors. These factors include:
- Number of isotopes: The more isotopes present in the mixture, the greater the average atomic mass will be.
- Isotopic masses: The mass of each individual isotope contributes to the overall average atomic mass.
- Abundance of each isotope: The relative abundance or percentage of each isotope in the mixture also affects the average atomic mass.
Therefore, the correct option is d) All of the above.
