Answer:
The atomic mass of silver is 107.86 amu
Explanation:
The atomic mass is calculated by formula
Atomic mass = (Mass of first isotope x Abundance of first isotope) + (Mass of Second isotope x Abundance of second isotope)
In case of silver, the formula will be as
Atomic mass = (Mass of Ag-107 x Abundance Ag-107) + (Mass of Ag-109 x Abundance Ag-109)
Mass of Ag- 107 = 106.9
Mass of Ag- 109 = 108.9
Abundance of Ag-107 = 51.82/100 = 0.5182
Abundance of Ag-109 = 48.18/100 = 0.4818
Putting these values in the formula
Atomic mass of silver = (106.9 x 0.5812) + (108.9 x 0.4818) = 107.86 amu
