Question

An object submerged into 50 cm^3 of water raises the water level to 65 cm^3. The mass of the object is 30 g. What is its density?

Answer 1

Answer:

Explanation:

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
