Answer: The atomic mass of silver is 107.8
Explanation:
Average atomic mass is the average mass of all the isotopes present depending on the relative abundance of each isotope.
Mass of isotope A = 106.9051
% abundance of isotope 1 = 51.82% = [tex]\frac{51.82}{100}[/tex]
Mass of isotope B = 108.9047
% abundance of isotope 2 = (100-51.82)% = [tex]\frac{48.18}{100}[/tex]
Formula used for average atomic mass of an element :
[tex]A=\sum[(106.9051)\times \frac{51.82}{100})+(108.9047)\times \frac{48.18}{100}]][/tex]
[tex]A=107.8[/tex]
Therefore, the average atomic mass of silver is 107.8
