What is benzene used for

Benzene is a colorless liquid with a sweet aroma and is widely used in various industries. Some of its common uses include:

  • Chemical feedstock: Benzene is a fundamental building block in the production of many chemicals, including plastics, resins, synthetic fibers, rubber, dyes, detergents, and pharmaceuticals.

  • Synthetic Fiber: It is used in the production of synthetic fibers like nylon and polyester.

  • Plastics and Polymers: Benzene is a major component in the production of plastics such as polystyrene and polyurethane.

  • Resins: It is used in the production of various resins, which are used in coatings, adhesives and sealants.

  • Rubber: Benzene is an ingredient in the production of synthetic rubber.

  • Dyes: It is used in the synthesis of dyes and pigments for coloring textiles and other products.

  • Pharmaceuticals: Benzene derivatives are used in the synthesis of many pharmaceuticals and drugs.

  • Solvent: Benzene was historically used as a solvent for a variety of substances, although its use as a solvent has declined due to its toxicity. Today safer alternatives are often chosen for this purpose.

It is important to note that benzene is a known carcinogen, and its use is regulated in many countries to reduce exposure and potential health risks. Safeguards and alternatives are often adopted in industries to reduce the risks associated with the use of benzene.

Benzene molar mass

The molar mass of benzene (C6H6) can be calculated by adding the atomic masses of its constituent atoms. Here are the atomic masses of the elements in benzene:

Carbon (C) atomic mass ≈ 12.01 g/mol
Hydrogen (H) atomic mass ≈ 1.01 g/mol

Now, calculate the molar mass of benzene:

Molar mass = (6 × atomic mass of C) + (6 × atomic mass of H)
= (6 × 12.01 g/mol) + (6 × 1.01 g/mol)
= 72.06 g/mol + 6.06 g/mol
= 78.12 grams/mol

Therefore, the molar mass of benzene is approximately 78.12 grams per mole.
