The percentage abundance is a measure of ratio of the number of each isotope and the total number of the element. The percentage abundance of each isotope is :
- Le - 19 = 0.32
- Le - 17 = 0.44
- Le - 15 = 0.24
Number of each isotope in the sample :
- Le - 19 = 16
- Le - 17 = 22
- Le - 15 = 12
Total number of sample = 50
The percentage natural abundance of the isotopes can be calculated :
Number of each isotope ÷ total number of sample
Percentage abundance of Le isotopes
- Le - 19 =
- Le - 17 =
- Le - 15 =
Therefore, the percentage abundance of Le - 19, Le - 17 and Le - 15 isotopes are 0.32, 0.44 and 0.24 respectively.
