There is now way to know.


Ag-107 has 47 protons and 60 neutrons. Ag-109 has 62 neutrons. A neutron has a mass of approximately 1, but when we add neutrons or protons to a nucleus there is a small conversion of mass into energy. So we can't know exactly what is the mass of an isotope knowing the mass of another. Maybe around 108.9 but this is just a guess.
