To calculate the unit mass of sodium carbonate (Na₂CO₃), you need to sum the molar masses of its constituent elements. The molar mass is calculated as follows: sodium (Na) has a mass of approximately 23 g/mol, carbon (C) is about 12 g/mol, and oxygen (O) is around 16 g/mol. Therefore, the unit mass of Na₂CO₃ is calculated as: (2 × 23) + (1 × 12) + (3 × 16) = 46 + 12 + 48 = 106 g/mol.

How do you calculate empirical formular mass?
To calculate the empirical formula mass, first determine the molar mass of each element in the empirical formula by using the periodic table. Multiply the atomic mass of each element by the number of times it appears in the formula. Finally, sum these values to obtain the total empirical formula mass. This value represents the mass of one empirical formula unit of the compound.
