An insulator or neither. The water inside of the sponge is what would conduct electricity.

The mass of the dry sponge would be less than 150 g since it absorbs water, so the initial mass of the sponge would be less than 150 g.
The body of a sponge is covered in tiny openings called pores. These pores allow water to flow in and out of the sponge, which helps the sponge filter out food particles and oxygen from the surrounding water.
It would sink.
You could first soak the sponge in water, then use the standard method of measuring irregular objects: fill a graduated cylinder with 100 mL of water, then drop in the wet sponge and see how much the water level rises.
Yes, water being absorbed into a sponge is a physical change because the water molecules are simply being taken up into the empty spaces within the sponge's structure. The water molecules do not undergo a chemical reaction that would alter their chemical composition.
No
Top opening of a sponge is called osculum . it is used to expel water out .
