Answer : The density of the rock is,
1.339g/cm^3

Explanation : Given,

Mass of the rock = 15 g

Initial volume = 25 ml

Increased volume = 36.2 ml

First we have to calculate the volume of the rock.

Volume of rock = Increased volume of water - Initial volume of water

Volume of rock = 36.2 ml - 25 ml = 11.2 ml

Now we have to calculate the density of rock.

Formula used :


Density=(Mass)/(Volume)

Now put all the given values in this formula, we get the density of the rock.


Density=(15g)/(11.2ml)=1.339g/ml=1.339g/cm^3

Conversion :
1ml=1cm^3

Therefore, the density of the rock is,
1.339g/cm^3
