The Composition of Sodium Carbonate (Na2CO3)
Before diving into the molecular weight of sodium carbonate, let’s break down its chemical composition:
- Sodium (Na): Sodium has an atomic mass of approximately 22.99 atomic mass units (amu).
- Carbon (C): Carbon has an atomic mass of approximately 12.01 amu.
- Oxygen (O): Oxygen has an atomic mass of approximately 16.00 amu.
- Sodium carbonate (Na2CO3) consists of two sodium atoms (Na), one carbon atom (C), and three oxygen atoms (O).
Calculating the Molecular Weight of Na2CO3
To find the molecular weight of sodium carbonate (Na2CO3), we sum the atomic masses of its constituent atoms according to the chemical formula:
Molecular Weight of Na2CO3 = (2 × Atomic Mass of Na) + Atomic Mass of C + (3 × Atomic Mass of O)
The Molecular Weight of Na2CO3 = (2 × 22.99 amu) + 12.01 amu + (3 × 16.00 amu)
Molecular Weight of Na2CO3 = 45.98 amu + 12.01 amu + 48.00 amu
Molecular Weight of Na2CO3 ≈ 105.99 amu
So, the mol weight of sodium carbonate (Na2CO3) is approximately 105.99 atomic mass units (amu) or 105.99 grams per mole (g/mol).
