Physics Question: It takes only 9.12N of force to hold up a 1KG metal crown in water.?

Question

Compute the specific gravity of this metal, and guess what element it might be using a density table.

How do I use this information to compute specific gravity? Once I find the specific gravity of this metal, then how do I determine its density? Is SG the same as its density?

Explanation / Answer

metal crown can sink of its own in water but force (up) is used to keep just under waterline > so its density is greater than water
