I think the answer is the "Caloris Basin".
Mercury is known for its dimbiness
Mercury is known for its dimbiness
The weight of an object that is 100 pounds on Earth would be approximately 38 pounds on Mercury. This is because Mercury's gravity is about 38% that of Earth's, so the object would weigh less on Mercury.
It depends what the object is.
Merury most well-known feature is The Caloris Basin.
If an object floats in water it will also float in the much denser mercury
Mercury itself is very poisonous. It collects in meat and tissue, as well, so mercury can carry over from anything that has consumed it. Fish are known for leading to mercury poisoning.

No spacecraft was needed in order to discover the planet Mercury. It's a "naked eye" object, and has been known as a morning-star/evening-star since ancient times.

Yes
The force of gravity on Mercury is about 3.7 meters per second squared, or 3.7 N/kg. The force of gravity on an object on Mercury will depend on the object's mass.
