- Fillarrow_forwardThe relative ratio, or percent, of each isotope found in nature is the abundance number used to calculate the average mass. Here's the general equation for average atomic mass: (Abundance A)(Mass A) + (Abundance B)(Mass B) = Atomic Mass For example, here's how the average mass of of boron was calculated. Percent Boron-10 Percent Boron-11 10 + 11 =10.81 amu 100 100 (.20)10 + (.80)11 = 10.8 amu %D 3. Let's try out the atomic mass equation. Suppose you have a mixture of two nitrogen isotopes. For every 1 Nitrogen-15 isotopes, there are 3 Nitrogen-14 isotopes. Determine the abundance of each isotope in this mixture. Predict the average atomic mass of this mixture. Hint: This is NOT the mixture of nitrogen found in nature. You can check your answer by clicking "My Mixture" under isotope mixture.
