How to Calculate the Percent Abundance of an Isotope | Sciencing

You could easily look up the percent abundance of each isotope in a chemistry book or on the Web, but you may have to calculate the percent abundance … For example, nitrogen (N) has two stable isotopes: N14 has a weight, rounded to three decimal places, of 14.003 atomic mass units (amu), with seven …

How to Calculate Percent Abundances | Sciencing

An isotope of an element is a variant in the nuclear makeup of the atom. Isotopes have different numbers of neutrons from atom to atom of the same element. The number of protons in the nucleus does not change from atom to atom. The mass number for every element is the number of protons and neutrons …

There are three isotopes of silicon. They have mass numbers of 28 …

The abundance of Si28 is 92.23%. Si29 is 4.68% and Si30 is 3.09%. Because most Si atoms have a mass of 28 amu, the average mass of all silicon atoms is very close to 28. Here is a video which summarizes how to calculate average atomic mass from data about mass and relative abundance.

How to find the percent abundance of 3 isotopes? | Yahoo Answers

total mass = 105.92 this is the weighted average of the 3 isotopes. X(104.93) + Y( 105.22) + Z(107.29) = 105.92 we also know that the abundance of each isotope must = 1. X + Y + Z = 1 you are missing information in this question. we need at least 1 number for the abundance of one of the isotopes.
