The masses of the ground and isomeric states in $^{124,125}$Ag have been measured using phase-imaging ion-cyclotron-resonance technique at JYFLTRAP double Penning trap mass spectrometer. $^{124}$Ag $^{125}$Ag were found to be 30(250) keV 250(430) less bound but 36 110 times more precise than Atomic Mass Evaluation 2020, respectively. excitation energy $^{124}$Ag$^{m}$, ${E_x = 188.2(25)}$ keV, was determined for first time. new values utilised study evolution nuclear structure via two-neutron separation energies. impact on astrophysical rapid neutron capture process has investigated neutron-capture reaction rate calculations. precision measurements indicate a linear trend energies reduce mass-related uncertainties $^{124}$Ag$(n,\gamma)^{125}$Ag by factor around 100. also improve $^{123}$Pd, previously as reference.
