Answer:
...
Explanation:
find density of salt solution 585g/500cc = 1.17g/cc
leaves density = 1.25g/cc, stars density = 1.12g/cc
Stars float, leaves sink. since everything is in g/cc, you do not have to worry about the info 1ml=1cc.
density = mass / volume.
density of salt solution = 585g(mass)/500cc(volume)
