Computing Molar Mass of Barium Carbonate Step by Step

Molar Mass of Barium Carbonate: Step-by-Step Calculation

1. Identify Element Counts

Read BaCO3 and list how many atoms of each element are present:

  1. 1 atom of Barium (Ba)
  2. 1 atom of Carbon (C)
  3. 3 atoms of Oxygen (O)

2. Determine Atomic Masses

Look up each element mass from the periodic table:

  1. Barium (Ba) ~= 137.327 g/mol
  2. Carbon (C) ~= 12.011 g/mol
  3. Oxygen (O) ~= 15.999 g/mol

3. Multiply Atomic Mass by Quantity

Multiply atom count by atomic mass for each element:

  • Barium (Ba): 1 x 137.327 = 137.330 g/mol
  • Carbon (C): 1 x 12.011 = 12.010 g/mol
  • Oxygen (O): 3 x 15.999 = 48.000 g/mol

4. Sum Total Molar Mass

Add all contributions to get the final molar mass in g/mol.

Molar Mass = (1 x 137.327 + 1 x 12.011 + 3 x 15.999)

Molar Mass = 137.330 + 12.010 + 48.000

Molar Mass = 197.330 g/mol

Final rounded value shown on this page: 197.33 g/mol.
