Molecular Mass: A Foundational Concept
The Molecular mass, also referred to as mole weight or molar mass, is a fundamental concept in chemistry. It denotes the mass of a single mole of a substance, commonly expressed in atomic mass units (amu) or unified atomic mass units (u). To calculate the molar mass of a compound, add the atomic masses of all its constituent atoms, considering their relative proportions.
Calculating the Molecular Mass of Sodium Carbonate
To calculate the mole mass of sodium carbonate (Na2CO3), we must first determine the atomic masses of the elements: sodium (Na), carbon (C), and oxygen (O), and then apply these values to the chemical formula.
- Sodium (Na): The atomic mass of sodium is approximately 22.99 amu.
- Carbon (C): The atomic mass of carbon is approximately 12.01 amu.
- Oxygen (O): The atomic mass of oxygen is approximately 16.00 amu.
Now, let’s calculate the molecular mass of sodium carbonate:
Molecular Mass of Na2CO3 = (2 × Atomic Mass of Na) + (1 × Atomic Mass of C) + (3 × Atomic Mass of O)
The Molecular Mass of Na2CO3 = (2 × 22.99 amu) + (1 × 12.01 amu) + (3 × 16.00 amu)
Molecular Mass of Na2CO3 = 45.98 amu + 12.01 amu + 48.00 amu
Molecular Mass of Na2CO3 = 105.99 amu
So, the molecular mass of sodium carbonate (Na2CO3) is approximately 105.99 amu.
