Calculate the molar mass of benzene

Benzene is a naturally occurring substance produced by volcanoes and forest fires and present in many plants and animals, but benzene is also a major industrial chemical made from coal and oil.

  • Benzene is one of the organic and simplest aromatic hydrocarbon and the parent compound of which has about a numerous number of important aromatic compounds.
  • The compound appears like a colourless liquid having a characteristic odour.
  • This compound is primarily utilized for producing polystyrene.


The chemical formula for benzene is C6H6. It shows that benzene has 6 hydrogen- H atoms and six-carbon atoms. The structure has a six-carbon ring which is represented by a hexagon and it includes 3-double bonds. The carbon atoms are represented by a corner that is bonded to other atoms.

Molar mass

To estimate the molar mass of any compound, we have to add up the molar masses of every atom of the given compound.

The molar masses of the atoms are

C:12.01 g/mol

H: 1.01 g/mol

multiply these values by however many of each element there is in the compound, so we would then have

C: 12.011 g/mol ×6= 72.066 g/mol

H :1.008 g/mol×6= 6.048g/mol

On adding the above masses we get

2.066 g/mol + 6.048g/mol= 78.114 g/mol


Molar mass of benzene is 78.114 g/mol
