Chapter 0, Problem C1.8(choose chapter or problem)
A sterling silver bracelet, which is 92.5% silver by mass, has a volume of \(25.6 cm^3\) and a density of \(10.2 g/cm^3\). (2.10, 4.5, 5.2, 5.4)
a. What is the mass, in kilograms, of the bracelet?
b. Determine the number of protons and neutrons in each of the two stable isotopes of silver: \({ }_{47}^{107} \mathrm{Ag} \quad{ }_{47}^{109} \mathrm{Ag}\)
c. Silver (Ag) has two naturally occurring isotopes: Ag-107 (106.905 amu) with an abundance of 51.84% and Ag-109 (108.905 amu) with an abundance of 48.16%. Calculate the atomic mass for silver.
d. Ag-112 decays by beta emission. Write the balanced nuclear equation for the decay of Ag-112.
e. A \(64.0-\mu \mathrm{Ci}\) sample of Ag-112 decays to 8.00 \(\mu \mathrm{Ci}\) in 9.3 h. What is the half-life of Ag-112?
