Mass=volume x density
if we have mass and density we can calculate volume using the formula: volume=mass/density
volume of the displaced water = 600g/19.3g/cm3
volume = 31.09cm3
Hydrogen and carbon atoms
Explanation:
Hydrocarbons are molecules that are made up of hydrogen and carbon atoms only.
They are made up of covalent bonds between the carbon and hydrogen atoms.
There is a wide range of hydrocarbons due to the unique properties of carbon.
Most of the hydrocarbons comes from crude oil, natural gas and coal.
When hydrocarbons burn, they produce water and carbon dioxide alone.
They are used as fuel in industrial processes because they produce heat energy.
