Answer:
Liquid, definite volume but no definite shape.
Explanation:
Density is given as mass / volume.
Mass is the sphere is 100 g.
Volume of the sphere = (pi∗r3)∗4/3

If you want to change the units to kg per cubic metres, then we need to divide this value by 1000( for g to kg) and multiply by 100 * 100 * 100 (for cm to m).
This makes the density to be 883.83 kg/m3
Molarity=moles/litre
molarity=0.5/0.1
molarity=5.00m
