Question

given that sulfurs atomic mass is 32.06 amu, what isotope of sulfur is most likely the most abundant?
sulfur-32
sulfur-33
sulfur-30
sulfur-31

Explanation:

Step1: Recall atomic - mass concept

The atomic mass of an element is a weighted - average of the masses of its isotopes, with the most abundant isotope having the greatest influence on the value.

Step2: Compare isotope masses

The atomic mass of sulfur is 32.06 amu. Among the given isotopes, sulfur - 32 has a mass closest to 32.06 amu.

Answer:

Sulfur-32
