tone arm with 10gr mass with 15 gram weight cartridge?

so for the actual mass of my arm to do all those calculationsת i need to add to the official spec of the manufacturer the weight of the screws and the lifter.
the headshell in my case ( well tempered) is part of the arm so i assume i was already taken into account.
i admit that i'll need to read yours explanation several times to completely understand it 😃
right now i am thinking about 3 carts, neither is Japanese.
Van den Hul DDT-II Special Moving Coil 
 Benz Micro Wood SL
E.A.T. JO N°5 CARTRIDGE.
the last one weight 15 g, while the first two are lighter, VDH 8.2 g, and benz micro *9 g.
so that was my major reason for asking that question .
also the EAT has COMPLIANCE, DYNAMIC/LATERAL           12 μm/mN
wile the VDH states- 

Compliance  15 without specifying which kind of value is it
so i'm confused with all that different values. 

I've used carts with 12-16g mass (16+ grams for Benz LPS) on my 9.5g EM Clearaudio tracer arm.  I just had to use the additional counterweight.  It sounded great, tracked well, and the resonance frequency as measured by the HiFi News test record was a hair over 7hz.  A bit low but turned out fine.

um = micron = one millionth of a meter.

if that was the question.

You can practice on the calculation chart that @yugiboy has posted.

With a well tempered you have variable damping to play with too, the raw resonance calculated for an undamped arm using the common formula won’t be the whole story.
