Interpretation : The argon’s three most abundant isotopesare to be identified.

Concept Introduction : The weighted average mass of the atoms in a naturally occurring sample of an element is the atomic mass.

Expert Solution & Answer

Answer to Problem 33LC

Argon-40 is the most abundant isotope of argon.

Explanation of Solution

Given information:

The three isotopes of argon are argon-36, argon-38, and argon-40.

The atomic mass of argon is 39.948 amu.

The weighted average mass of the atoms in a naturally occurring sample of an element is the atomic mass.

Compare the atomic mass to the mass of each isotope.

Find the mass of the isotope whole value is closer to atomic mass.

Among the three given isotopes, the mass of argon-40 is closer to atomic mass.

So, argon-40 is the most abundant isotope than argon-36 and argon-38.
