Answer is: the molar mass od sodium carbonate (Na₂CO₃) is 106.0 g/mol.

M (Na₂CO₃) = 2 · Ar (Na) + Ar (C) + 3 · Ar (O).

M (Na₂CO₃) = 2 · 23 + 12 + 3 · 16 · g/mol.

M (Na₂CO₃) = 46 + 12 + 48 · g/mol.

M (Na₂CO₃) = 106 g/mol; molar mass of sodium carbonate.

Ar is relative atomic mass (the ratio of the average mass of atoms of a chemical element to one unified atomic mass unit) of an element.
