Question
Silver has two naturally occurring isotopes (Ag-107 and Ag-109).
(a) Use the periodic table to find the atomic mass of silver.
(b) If the natural abundance of Ag-107 is 51.84%, what is the natural abundance of Ag-109?
(c) If the mass of Ag-107 is 106.905, what is the mass of Ag-109?

Answers
a). Look it up on the periodic table.
b). If the total is 100 and one is 51.84, wouldn't the other one be 100-51.84?
c). mass107*fraction + mass109*fraction = atomic mass Ag.
Post your work if you get stuck.
