II. Full Form and Structure of Sodium Carbonate (Na2CO3):

Sodium carbonate has the chemical formula Na2CO3, indicating that each molecule consists of two sodium (Na) atoms, one carbon (C) atom, and three oxygen (O) atoms. The structure of sodium carbonate is composed of a sodium cation (Na+) and a carbonate anion (CO3²⁻) held together by ionic bonds.

III. Atomic Masses of Constituent Elements:

To calculate the molar mass of sodium carbonate, we need the atomic masses of its constituent elements. As of my last knowledge update in January 2022, the approximate atomic masses are:

• Sodium (Na): 22.99 g/mol
• Carbon (C): 12.01 g/mol
• Oxygen (O): 16.00 g/mol

IV. Calculation of Molar Mass na2co3 :

Now, let’s perform the calculation step by step:

1. Sodium (Na): 2 atoms * 22.99 g/mol = 45.98 g/mol
2. Carbon (C): 1 atom * 12.01 g/mol = 12.01 g/mol
3. Oxygen (O): 3 atoms * 16.00 g/mol = 48.00 g/mol

Adding these values together:
[ Molar\ Mass\ (Na2CO3) = 45.98\ g/mol + 12.01\ g/mol + 48.00\ g/mol ]

[ Molar\ Mass\ (Na2CO3) = 105.99\ g/mol ]

So, the molar mass of sodium carbonate is approximately 105.99 g/mol.
