Silver has an atomic mass of 107.868 amu.The Ag-109 isotope (108.905 amu)is 48.16%.What is the amu of the other isotope?

Question

Quizplus · Accepted Answer

The average atomic mass of silver is calculated using the isotopic masses and their relative abundances. Given that Ag-109 has a mass of 108.905 amu and an abundance of 48.16%, we can denote the mass of the other isotope as $x$ and its abundance as $100\% - 48.16\% = 51.84\%$. The equation to find the average atomic mass is: $$107.868 = (108.905 \times 0.4816) + (x \times 0.5184)$$. Solving for $x$ gives $x \approx 106.905$ amu.
