Question

calculate the average atomic mass of silver using the isotopic composition data given in the following table. isotope mass percent abundance silver - 105 105 48% silver - 108 108 43% silver - 109 109 9%

Explanation:

Step1: Convert percentages to decimals

For Silver - 105: \(48\%=0.48\)
For Silver - 108: \(43\% = 0.43\)
For Silver - 109: \(9\%=0.09\)

Step2: Calculate the contribution of each isotope

Contribution of Silver - 105: \(105\times0.48 = 50.4\)
Contribution of Silver - 108: \(108\times0.43=46.44\)
Contribution of Silver - 109: \(109\times0.09 = 9.81\)

Step3: Sum up the contributions

\(50.4+46.44 + 9.81=106.65\)

Answer:

\(106.65\)
