Computing Molar Mass of Barium Hydrogen Carbonate Step by Step
Molar Mass of Barium Hydrogen Carbonate: Step-by-Step Calculation
1. Identify Element Counts
Read Ba(HCO3)2 and list how many atoms of each element are present:
- 1 atom of Barium (Ba)
- 2 atoms of Hydrogen (H)
- 2 atoms of Carbon (C)
- 6 atoms of Oxygen (O)
2. Determine Atomic Masses
Look up each element mass from the periodic table:
- Barium (Ba) ~= 137.327 g/mol
- Hydrogen (H) ~= 1.008 g/mol
- Carbon (C) ~= 12.011 g/mol
- 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
- Hydrogen (H): 2 x 1.008 = 2.020 g/mol
- Carbon (C): 2 x 12.011 = 24.020 g/mol
- Oxygen (O): 6 x 15.999 = 95.990 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 + 2 x 1.008 + 2 x 12.011 + 6 x 15.999)
Molar Mass = 137.330 + 2.020 + 24.020 + 95.990
Molar Mass = 259.360 g/mol
Final rounded value shown on this page: 259.36 g/mol.
