How do you determine the molar mass of heptane?
To determine the molar mass of any molecule, we must add up the atomic mass of each atom that makes up that molecule.
The molar mass of heptane is 100.23 g/mol.
To determine the molar mass of Heptane, we must add up the atomic mass of each atom that makes up heptane. The chemical composition of heptane is C7H16. This means there are 7 carbon atoms and 16 hydrogen atoms. Tha atomic weight of each atom can be found on most periodic tables, many of which are accessible online.
Carbon - 12.01 u
Hydrogen - 1.01 u
Molar mass of heptane:
(7 x 12.01) +(16 x 1.01) = 100.23 g / mol
