Well Zach I'm afraid I'm not sure we can answer this one. Nobody knows what dark matter actually is let alone what it weighs! There are a few theories out there but no clear answer on the mass of dark matter. It might vary just like normal matter, or it might be super-heavy (like a neutron star, see your other question).
Measuring it in your hand would certainly be tricky. It would probably move straight through your hand – there would be no way to ‘hold’ it. It would have a ‘weight’ though as weight is just a measure of gravitational force, and we do know that dark matter interacts with gravity as does normal matter.
If you know where to get hold of a handful of dark matter let us know and we’ll work out how to weigh it!
