Chlorine, which has an atomic mass of 35.453 amu, has two naturally occurring isotopes, cl-35 and cl-37. which isotope occurs in greater abundance?

The isotope that occurs in greater abundance is Cl-35

We can obtain the answer to the question by simply calculating the abundance of each isotope.

Let isotope Cl-35 be A

Let isotope Cl-37 be B

From the question given above, the following data were obtained:

Mass of A = 35

Mass of B = 37

Atomic mass of chlorine = 35.453 amu

35.453 = [(35 × A%)/100] + [(37 × (100 – A%))/100]

35.453 = 0.35A% + 37 – 0.37A%

35.453 – 37 =  0.35A% – 0.37A%

–1.547 = –0.02A%

A% = –1.547 / –0.02

Abundance of B (B%) = 100 – 77.35

Isotope Cl-35 has abundance of 77.35%

Isotope Cl-37 has abundance of 22.65%

Therefore, isotope Cl-35 occurs in greater abundance.

Cl-35 occurs in greater abundance.

The weighted atomic mass lies closer to 35 u than to 37 u, so the Cl-35 isotope must be more abundant.
