Density describes how much mass is contained in a certain volume knowing how far apart molecules are in each state , which best ranks soilds liquids and gasses from least dense to most desnse ?

Knowing how far apart molecules are in each state best ranks solids, liquids, and gases from least dense to most dense.

Density describes how much mass is contained in a certain volume

That is the definition of density: Density = mass/volume.

If you keep the volume constant but make the molecules closer together, you will be able to pack in more molecules (more mass).

In solids, the molecules are close together. They have the most mass in a given volume, so they have the greatest density.

In gases, the molecules are far apart. They have the least mass in a given volume, so they have the smallest density.

In liquids, the molecules are a little further apart than in solids. Thus, their density is between that of liquids and gases.

where are the choice options?

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
