In this article, we will delve into the concept of mol mass, explore its significance in chemistry, and calculate the mol mass of benzoic acid.

Benzoic Acid Molar Mass

Molar Mass: A Key Concept

Molar mass, also known as molecular weight, is a fundamental concept in chemistry. It represents the mass of one mole of a substance and is typically expressed in atomic mass units (amu) or unified atomic mass units (u). Calculating the molar mass of a compound involves summing the atomic masses of all the constituent atoms in its chemical formula while considering their respective proportions.

Calculating the Molar Mass of Benzoic Acid

To calculate the mol mass of benzoic acid (C7H6O2), we must determine the atomic masses of the elements: carbon (C), hydrogen (H), and oxygen (O), and then apply these values to the chemical formula.

1. Carbon (C): The atomic mass of carbon is approximately 12.01 amu.
2. Hydrogen (H): The atomic mass of hydrogen is approximately 1.01 amu.
3. Oxygen (O): The atomic mass of oxygen is approximately 16.00 amu.

Now, let’s calculate the molar mass of benzoic acid:

Molar Mass of C7H6O2 = (7 × Atomic Mass of C) + (6 × Atomic Mass of H) + (2 × Atomic Mass of O)

Molar Mass of C7H6O2 = (7 × 12.01 amu) + (6 × 1.01 amu) + (2 × 16.00 amu)

The Molar Mass of C7H6O2 = 84.07 amu + 6.06 amu + 32.00 amu

Molar Mass of C7H6O2 = 122.13 amu

So, the mol mass of benzoic acid (C7H6O2) is approximately 122.13 amu.
