Arock weighing 75.0 g is placed in a graduated cylinder displacing the volume from 31.4 ml to 36.5 ml. what is density of the rock in grams/cubic centimeter?

The density of the rock will be

Explanation:

Density is defined as the mass contained per unit volume.

Given :

Mass of rock = 75.0 grams

Volume of water displaced = (36.5-31.4) ml = 5.1 ml

Putting in the values we get:

Thus density of the rock will be

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
