Quizplus · Accepted Answer

The isotopic mass of $^{109}Ag$ can be calculated using the formula for average atomic mass: $\text{average atomic mass} = (f_1 \times m_1) + (f_2 \times m_2)$, where $f$ represents the fractional abundance and $m$ represents the isotopic mass. Rearranging to solve for $m_2$ (the mass of $^{109}Ag$) and substituting the given values, we find that $m_2 = 108.91$ amu.

The Average Atomic Mass of Silver Is 107
