The density of certain substances are listed as follows:
- The density of liquid water is approximately 1000 kg/cubic meter.
- The density of gaseous air is 1.22521 kg/cubic meter.
- The density of ice (solid water) is approximately 910 kg/cubic meter.
- Finding the Weight of the Substance in the Question
- Turning This Value into Tonnes
The same formula will work with any kind of substance, whether liquid or solid. However, there is a vast difference between the volume of a substance, and the mass of that volume. To be sure of the mass of something if it is gaseous or liquid, you need to know the density of the substance that is being converted, in order to get its mass. Without the density, you will not be able to know how much mass is in the volume you are working with.
