Concept introduction:
Atomic mass of an element is the weighted average mass of the isotopes of that element.
Answer to Problem 71A
Atomic mass of sulfur is
Explanation of Solution
Given Information:
Calculation:
Atomic mass of an element is the sum of mass contribution of the isotopes of that element.
Atomic mass:
Percent Abundance: 94.99%
Atomic mass:
Percent Abundance: 0.75%
Atomic mass:
Percent Abundance: 4.25%
Atomic mass:
Percent Abundance: 0.01%
Atomic mass of sulfur will be 32.065
Thus,
Mass contribution of
Mass contribution of
Mass contribution of
Mass contribution of
