Ageology student found an irregularly shaped rock, with a mass of 28.63 grams, and placed it into a graduated cylinder with a volume of 13.31 ml water. if the water level increased to 19.73 ml after the rock was placed in, what is the density of the rock, in g/ml?

Answer : The density of the rock is, 4.459 g/ml

Explanation : Given,

Mass of the rock = 28.63 g

Initial volume of water = 13.31 ml

Increased volume of water = 19.73 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 = 19.73 ml - 13.31 ml = 6.42 ml

Now we have to calculate the density of rock.

Formula used :

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

Therefore, the density of the rock is, 4.459 g/ml
