Dear T_bone, if you have the resonance frequency with a given cartridge and know its compliance this formula will lead you to the effective mass:
F(r) = 1000 / 2 x P x ((M(t) + M(c)) x compliance)
F(r) = resonance frequency
P = Phi = 3,1482
M(t) = mass (effective) of tonearm
M(c)= mass (weight) of cartridge
Best regards.
