Answer:
The atomic mass of the other isotope = 106.905 amu
Explanation:
Step 1: Data given
Atomic mass of silver = 107.868 amu
Ag109 isotope has an atomic mass of 108.905 amu = 48.16 %
Step 2: Calculate the abundance of the other isotope
100.0 % - 48.6 % = 51.84 %
107.868 = 0.4816*108.905 + 0.5184*X
55.419352 = 0.5184X
X = 106.905
The atomic mass of the other isotope = 106.905 amu
