Silver has 2 isotopes Ag-107 and Ag-109. The percent abundance of Ag-107 is 51.35 % and that of Ag-109 is 48.65%. Find the avera

7nadin3 [17]

Given:

Isotopes of silver with atomic masses:

Ag - 107 and Ag - 109

% Abundance of Ag-107 = 51.35 %

% Abundance of Ag-109 = 48.65 %

To determine:

The average atomic mass of Ag

Explanation:

The average atomic mass can be calculated using the formula-

Average Atomic Mass = f1M1 + f2M2 + .......+fnMn

where:

f = fraction representing the abundance of that isotope

M = atomic mass of that isotope

In the case of silver

Average atomic mass = (51.35/100)*107 + (48.65/100)*109

= 54.9445 + 53.0285 = 107.973 amu

Ans: the average atomic mass for silver is 107.973 amu
