Ethanol, a member of a class of organic compounds that are given the general name alcohols. Ethanol is an important industrial chemical; it is used as a solvent, in the synthesis of other organic chemicals, and as an additive to gasoline. It is also the intoxicating ingredient of many alcoholic beverages.

We can rearrange this to get the expression for the mass. m = d×V. Example: If 500 mL of a liquid has a density of 1.11 g/mL, what is its mass?
Density is the amount of matter in an object compared to its volume (the amount of space it takes up). If an object were extremely dense, it would feel heavier than another object of the same size that was less dense. For example, a 1-litre soda bottle filled with air would feel much lighter than the same bottle filled with water. Water has a density of 1 kilogram per liter, while air has a density of 0.000129 kilograms per liter. Water contains almost one thousand times more matter than the same volume of air would, therefore it is denser.
