Asmall rock with a mass of 6 grams is dropped into a graduated cylinder with 20ml of water. the water rises to 23ml .what is the density of the rock.

Explanation:

As it is given that mass is 6 grams. Therefore, volume occupied by the rock is as follows.

                   Volume = final volume - initial volume

                                 = 23 ml - 20 ml

                                 = 3 ml

Since, density is defined as the amount of mass present in per unit volume of a substance.

Mathematically,            Density =

Therefore, putting the given values into the above formula as follows.

                          Density =

                                        =

                                         = 2 g/ml

Thus, we can conclude that density of the rock is 2 g/ml.

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
