The density of the object is 2 g/cm³
Density of an object is defined as the mass of the object per unit volume of the object i.e
Density = mass / volume
To obtain the answer to the question given above, we'll begin by calculating the volume of the object. This can be obtained as follow:
Volume of water = 50 cm³
Volume of water + Object = 65 cm³
Volume of object =?
Volume of object = (Volume of water + Object) – (Volume of water)
Volume of object = 65 – 50
Volume of object = 15 cm³
Finally, we shall determine the density of the object. This can be obtained as follow:
Volume of object = 15 cm³
Mass of object = 30 g
Density of object =?
Density = mass / volume
Density = 30 / 15
Density of object = 2 g/cm³
Therefore, the density of the object is 2 g/cm³
