# How would you calculate the average atomic mass of element,X, if a sample of X is 22.50% x-37 and 77.50% x-35.?

Average atomic mass

Divide each of the percentages by 100 to convert them to decimals, then multiply the results by the corresponding mass and add them together.

To calculate the average atomic mass of element X, you would multiply the percent abundance of each isotope by its respective atomic mass, then sum these products together.

For X-37: (22.50/100) * atomic mass of X-37

For X-35: (77.50/100) * atomic mass of X-35

Then, add these two values together to find the average atomic mass of element X.

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.
