Calcium has three different isotopes. One has a mass of 35.00 amu; another has a mass of 41.00 amu; and another has a mass of 40.00 amu. Which isotope is the most abundant of the three?

Answer 1

The quoted atomic mass on the Periodic Table is the weighted average of the individual isotopes. The most abundant isotope should be #""^40Ca#.

It follows that whatever atomic mass is quoted on the Periodic Table, the most abundant isoptope of that element must make the greatest statistical contribution. Calcium has an atomic mass of #40.07# #g*ml^-1#. Without looking up the isotopic distribution, clearly #""^40Ca# is the most abundant isotope.

Answer 3

To determine which isotope of calcium is the most abundant, we need to consider the relative abundance of each isotope along with its mass. The isotope with the highest relative abundance is the most abundant. Unfortunately, the question does not provide information about the relative abundance of each isotope. Without this information, we cannot definitively determine which isotope of calcium is the most abundant. Therefore, based solely on the provided masses, we cannot identify the most abundant isotope.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
