Question

chlorine has two naturally occuring isotopes chlorine-35 and chlorine-37.If the average atomic mass of chlorine is 35.5amu which isotope is the most abundant?Explain.

Answer 1

Answer:35.5 amu is more abundant

Explanation:

35.5={x(35)+(100-x)37}/100

Or, 3550=3700-2x

Or, 2x=3700-3550

x=150/2=75

Thus, % of cl 35 is 75% and that of cl 37 is 25%.

Answer: chlorine 35 is more abundant
