Molar Mass: An Essential 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 mol mass of a compound involves summing the atomic masses of all the constituent atoms in its chemical formula, taking into account their respective proportions.
Calculating the Molar Mass of Sulfuric Acid
To calculate the mol mass of sulfuric acid (H2SO4), we must determine the atomic masses of the elements: hydrogen (H), sulfur (S), and oxygen (O), and then apply these values to the chemical formula.

- Oxygen (O): The atomic mass of oxygen is approximately 16.00 amu.
Now, let’s calculate the mol mass of sulfuric acid:
Molar Mass of H2SO4 = (2 × Atomic Mass of H) + (1 × Atomic Mass of S) + (4 × Atomic Mass of O)
The Molar Mass of H2SO4 = (2 × 1.01 amu) + (1 × 32.07 amu) + (4 × 16.00 amu)
Molar Mass of H2SO4 = 2.02 amu + 32.07 amu + 64.00 amu Molar Mass of H2SO4 = 98.09 amu
So, the mol mass of sulfuric acid (H2SO4) is approximately 98.09 amu.
