Density of Common Alkanes
Alkanes are relatively less dense than water, and their densities range from about 600 to 800 kg/m3. The specific density of a particular alkane will depend on its molecular structure and the arrangement of carbon and hydrogen atoms within the molecule.
The following table provides a comprehensive list of density values for common alkanes at 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
