Answer to Problem 32LC
The atomic masses of elements are generally not whole numbers because the atomic mass value depends on the isotope mass and relative abundance which might not be a whole number.
Explanation of Solution
The weighted average mass of the atoms in a naturally occurring sample of an element is the atomic mass.
The mass and relative
The weighted average of all an element's isotopes' masses is used to determine an element's atomic mass. The foundation rests on relative abundance.
For the calculation of atomic mass, multiply each isotope's mass by its natural abundance, represented as a decimal, and add on the products.
The atomic masses of elements are generally not whole numbers because the atomic mass value depends on the isotope mass and relative abundance which might not be a whole number.
