Molar Mass of Na2CO3

How to work out the molar mass of Na2CO3

  1. Count the atoms of each element in Na2CO3: 2 Na, 1 C and 3 O.
  2. Multiply each count by the element's atomic weight: 2 × 22.990 = 45.980; 1 × 12.011 = 12.011; 3 × 15.999 = 47.997.
  3. Add the results: 45.980 + 12.011 + 47.997 = 105.988 g/mol.
