1. Find the atomic masses of each element:
* Sodium (Na): 22.99 g/mol
* Carbon (C): 12.01 g/mol
* Oxygen (O): 16.00 g/mol
2. Multiply the atomic mass of each element by its subscript in the formula:
* Sodium: 22.99 g/mol * 2 = 45.98 g/mol
* Carbon: 12.01 g/mol * 1 = 12.01 g/mol
* Oxygen: 16.00 g/mol * 3 = 48.00 g/mol
3. Add the masses together:
45.98 g/mol + 12.01 g/mol + 48.00 g/mol = 105.99 g/mol
Therefore, the molar mass of sodium carbonate (Na₂CO₃) is approximately 106 g/mol to the nearest gram.
