The average atomic mass of nickel is 58.693 amu.Given the data in the following table,what is the natural abundance of nickel-64?

Question

Quizplus · Accepted Answer

To find the natural abundance of nickel-64, we need to determine the percent abundance of each isotope and add them up. We are given the mass and natural abundance for each isotope of nickel except for nickel-64.

Let x be the percent natural abundance of nickel-64. Then,

(68.0769)+(26.2231)+(1.1399)+(3.6345)+(x) = 100
99.0744 + x = 100
x = 0.9256%

Therefore, the natural abundance of nickel-64 is 0.9256%.

The Average Atomic Mass of Nickel Is 58
