How do you calculate the atomic mass of an element with different isotopes?

Answer 1

To calculate average Atomic Mass from different isotopes of an element, we take into account the relative atomic masses of isotopes and their relative abundance on Earth. The following formula is used to calculate the needful :

atomic mass = mass of isotope x percent abundance + mass of isotope x percent abundance / 100 (whole expression divided by 100)

Answer 2

Multiply the atomic mass of each isotope by its relative abundance (expressed as a decimal). Add the products together to find the weighted average atomic mass of the element.

Answer 3

all the different isotopes are averaged in together to find the atomic mass

Answer 4

Isotopes are any of the several different forms of an element each having different atomic mass (mass number). Isotopes of an element have nuclei with the same number of protons.

Answer 5

The mass number is the sum of protons and neutrons in the atomic nucleus.

Answer 6

divide by pi
