There will be less noise for the neighbors.

will it make the same damage as it would in a regular room?
like what will be the damage in a vacuum chamber and will there be a big difference if in a room with normal atmosphere

will it make the same damage as it would in a regular room?

The fragmentation holes in the walls will be a bit deeper.

Hey, you have sinister plans with this, or what ?
Any practical application ? Will be hard to pull the pin and get out and then suck out all the air in a few seconds ...
Explosive doesn't need atmosphere; damage will be about the same.

The type of grenade (Fragmentation or Concussion) might make a difference.

Also heavily depends on the type of damage you consider. Assuming the room is large enough there won't be a pressure wave to consider, meaning that energy rather goes into shrapnel speed. So, you might perforate the well extremely well, but the structure might remain standing.
