Arock weighing 15.0g is placed in a graduated cylinder, displacing the volume from 25.0 ml to 36.2 ml. what is the density of the rock in grams/cubic centimeter?

Answer : The density of the rock is,

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 :

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

Conversion :

Therefore, the density of the rock is,

first one is the correct answer

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
