For example, the atomic weight of the element chlorine is 35.453, determined by averaging the atomic masses and relative abundances of its two main naturally occurring isotopes, which have atomic masses of about 35 and 37.
Question 3: Calculate the average atomic mass of the chlorine which has two naturally occurring isotopes. The Percent abundance of 35 Cl (mass = 34.969 amu) is 75.53% and the percent abundance of 37 Cl (mass = 36.966 amu) is 24.47%.
