There *is* a line somewhere that says the hull armour is 'solid neutronium'...

The hull armour is not "solid neutronium", it contains neutronium according to the Acclamator-entry in AotC:ICS.

According to the same source the vessels can accelerate "for hours" with "thousands of Gs", so we can be certain, that the ships don't run at full power all the time, but only for a small fraction of that.

Can we use that to calculate the density of the fuel, if we assume 10% or 20% of the ship's volume to be fuel-tanks?

Well, sue me for not knowing the exact line

Also remember that if inertial compensators are a thing, it's possible they have some sort of magic mass-lightening going on. I don't recall that there was ever any inertial compensation mentioned in canon, but there's definitely gravity generators (see curious lack of zero-gee aboard ISD's and other craft) so it's not impossible.

Well frankly there has to be some kind of inertial damping happening, since the ships maintain a 1g environment for the crew while accelerating at thousands of g's in a direction perpendicular to the gravity.

Inertial Compensators are mentioned in the X-Wing-novels among other sources, so if they exist for the fighters, the big ships would have them, too.

With 1000s of gees of acceleration they'd better.
Not that I see what acceleration compensation has to do with mass lightening.

I might have been mixing up my fictional sciences. Mass lightening doesn't really have anything to do with acceleration compensation. Gravity generation on the other hand might. If you can create an artificial mass (essentially what's required for gravity generation, isn't it? Unless they're wearing magnetic boots or something) you might be able to reverse the effect and artificially reduce perceived mass... but who knows.

DarkStar took a pretty deep dive into estimating density of SW ships in this blog post, based on some scenes from the clone wars where starship debris rapidly sink to the bottom of the ocean. Then based on volume, it would run into billions of tons probably more than ten billion tons.

Alternatively. ~173 billion tons

More usefully, he's also got a decent-looking list of starship volumes here, which puts the Ex at about 800 times the volume of a VenStar. He's using Saxton's 17.6km estimate, rather than the later 19km statement, so the actual ratio is about 1:1000.

A VenStar has a peak acceleration of 3000g and peak reactor output of 3.6E24J. Using P=mac, I find that this gives a VenStar a mass of 4E11kg. From the above, assuming roughly equal densities, the Ex is about a thousand times that, so its mass would be roughly 400 billion tons.

at what point would you have to start worrying about the gravitational pull of vessels this size? would an executor or eclipse class in orbit create tidal effects? the death star probably did.

as to the fuel question, is hypermatter FTL? if so, would harnessing and slowing it down make it begin to give off energy in a kind of reversal to the exponential increases necessary to propel an object to the speed of light from the other side?
