A straightforward method of finding the density of an object is to measure its mass and then measure its volume by submerging it
Thepotemich [5.8K]

Answer:

<em>The density of rock = 3.37 g/cm³</em>

Explanation:

Density: Density can be defined as the ratio of the mass of a body to the volume. The S.I unit of density is kg/m³. It can be expressed mathematically as ,

D = M/V............................................... Equation 1

Where D = density of the body, M = mass of the body, V = volume of the body.

From Archimedes' principle, a body will displace a volume of water equal to  its volume.

Therefore, Volume of the object = volume of water displaced

<em>Given: M = 300 g, V = volume of water displace = 89.0 cm³.</em>

<em>Substituting these values into equation 1</em>

<em>D = 300/89</em>

<em>D = 3.37 g/cm³</em>

<em>The density of rock = 3.37 g/cm³</em>
