Density of a substance can be defined as the mass of that substance per unit volume.
[tex] Density = \frac{Mass}{Volume} [/tex]
Given the mass of object = 9.0 g
Volume of the object will be the volume of water displaced by the object
So, volume of the object = [tex] 13cm^{3} [/tex]
Calculating the density from mass and volume:
[tex] Density = \frac{9.0 g}{13 cm^{3}} [/tex]
= 0.69 [tex] \frac{g}{cm^{3}} [/tex]
Therefore, the density of given object is 0.69 [tex] \frac{g}{cm^{3}} [/tex]
