Benzoic Acid Molecular Weight

Molecular Weight: A Fundamental Concept

Molecular weight, also known as molar mass, is a fundamental concept in chemistry. It represents the mass of one mole of a specific substance and is typically expressed in atomic mass units (amu) or grams per mole (g/mol). A mole is a unit used to quantify the amount of a substance and contains approximately 6.022 x 10^23 entities, known as Avogadro’s number. The molecular weight is numerically equivalent to the atomic or molecular weight of the substance.

The Molecular Weight of Benzoic Acid (C7H6O2)

To calculate the molecular weight of benzoic acid (C7H6O2), we need to consider the atomic masses of its constituent elements: carbon (C), hydrogen (H), and oxygen (O).

• The atomic mass of carbon (C) is approximately 12.01 amu.
• The atomic mass of hydrogen (H) is roughly 1.01 amu.
• The atomic mass of oxygen (O) is approximately 16.00 amu.

Now, let’s calculate the molecular weight of benzoic acid by adding up the atomic masses of each element in its chemical formula:

mole Weight of Benzoic Acid (C7H6O2) = (7 x Atomic Mass of C) + (6 x Atomic Mass of H) + 2 x Atomic Mass of O)

mole Weight of Benzoic Acid (C7H6O2) ≈ (7 x 12.01 amu) + (6 x 1.01 amu) + (2 x 16.00 amu)

The mole Weight of Benzoic Acid (C7H6O2) ≈ 84.07 amu + 6.06 amu + 32.00 amu

mole Weight of Benzoic Acid (C7H6O2) ≈ 122.13 amu
