Molar mass of BaCl2 (Barium chloride)
The molar mass of BaCl2 is 208.24 g/mol.
Used to test for sulfate ions (white precipitate) and gives a green flame.
Step-by-step calculation
Add up the atomic masses of every atom in the formula:
1 × 137.33 + 2 × 35.453 = 208.24 g/mol
| Element | Atoms | Atomic mass (u) | Subtotal (g/mol) | % by mass |
|---|---|---|---|---|
| Barium (Ba) | 1 | 137.33 | 137.330 | 65.95% |
| Chlorine (Cl) | 2 | 35.453 | 70.906 | 34.05% |
| Molar mass of BaCl2 | 208.24 g/mol | |||
Moles to grams for BaCl2
Multiply the number of moles by 208.24 g/mol to get the mass, and divide a mass by 208.24 g/mol to get the moles.
