Computing Molar Mass of Barium Fluoride Step by Step
Molar Mass of Barium Fluoride: Step-by-Step Calculation
1. Identify Element Counts
Read BaF2 and list how many atoms of each element are present:
- 1 atom of Barium (Ba)
- 2 atoms of Fluorine (F)
2. Determine Atomic Masses
Look up each element mass from the periodic table:
- Barium (Ba) ~= 137.327 g/mol
- Fluorine (F) ~= 18.998 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
- Fluorine (F): 2 x 18.998 = 38.000 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 + 2 x 18.998)
Molar Mass = 137.330 + 38.000
Molar Mass = 175.320 g/mol
Final rounded value shown on this page: 175.32 g/mol.
