A scale reads 20.3 N when an object is not submerged in water and 20.0 N when the object is (completely) submerged in water.

What is the specific gravity of the object?

well, it has .3N of bouyancy.

that is equivalent to what volume of water?

.3=densitywater*g*volume
solve for volume

then density= weight/volume=20.3/volume

and specfic gravity= denstiy/denstiywater.
