Molecular Mass: An Essential Concept
Mole mass, also known as molecular weight or molar mass, is a fundamental concept in chemistry. It signifies a molecule’s mass, conveyed in atomic mass units (amu) or unified atomic mass units (u). Molecular mass is computed by summing the atomic masses of all the atoms in the molecule, factoring in their proportions.
Calculating the Molecular Mass of Sulphuric Acid
To determine the molecular mass of H2SO4, we add the atomic masses of hydrogen (H), sulfur (S), and oxygen (O) within the compound’s formula.
- Hydrogen (H): The atomic mass of hydrogen is approximately 1.01 amu.
- Sulfur (S): The atomic mass of sulfur is approximately 32.07 amu.
- Oxygen (O): The atomic mass of oxygen is approximately 16.00 amu.
Now, let’s calculate the molecular mass of sulphuric acid:
Mole Mass of H2SO4 = (2 × Atomic Mass of H) + (1 × Atomic Mass of S) + (4 × Atomic Mass of O) Mole Mass of H2SO4 = (2 × 1.01 amu) + (1 × 32.07 amu) + (4 × 16.00 amu) Mole Mass of H2SO4 = 2.02 amu + 32.07 amu + 64.00 amu Mole Mass of H2SO4 = 98.09 amu
So, the mole mass of sulphuric acid (H2SO4) is approximately 98.09 amu.

Molar Mass: A Fundamental Concept
The Molar mass is a fundamental concept in chemistry that is crucial for various calculations in the field. It represents the mass of one mole of a substance, and it is expressed in grams per mole (g/mol). The molar mass of a compound is calculated by summing the atomic masses of all the atoms in its chemical formula, taking into account the number of atoms of each element. This value plays a vital role in stoichiometry, where it helps in determining the number of moles, mass, or volume of substances involved in chemical reactions.
Calculating the Molar Mass of Sulphuric Acid
To calculate the molar mass of sulphuric acid (H2SO4), we need to determine the atomic masses of the elements hydrogen (H), sulfur (S), and oxygen (O) and then apply these values to the chemical formula.
- Hydrogen (H): The atomic mass of hydrogen is approximately 1.01 g/mol.
- Sulfur (S): The atomic mass of sulfur is approximately 32.07 g/mol.
- Oxygen (O): The atomic mass of oxygen is approximately 16.00 g/mol.
Now, let’s calculate the molar mass of sulphuric acid:
Mol Mass of H2SO4 = (2 × Atomic Mass of H) + (1 × Atomic Mass of S) + (4 × Atomic Mass of O)
The Mol Mass of H2SO4 = (2 × 1.01 g/mol) + (1 × 32.07 g/mol) + (4 × 16.00 g/mol)
