Help me answer this chemistry question. thank you!
tatiyna

Answer:

78.85

Explanation:

To <u>calculate the average atomic mass of the isotopes </u>we use the <em>given masses and abundances</em>, as follows:

  • Mass of Isotope 1 * Abundance of Isotope 1 + Mass of Isotope 2 * Abundance of Isotope 2 + ....

In other words:

  • 78 amu * 75/100 + 81 amu * 15/100 + 82 amu * 10/100 = 78.85

So the answer is 78.85.
