Computing Molar Mass of Chromium(III) Fluoride Step by Step
Molar Mass of Chromium(III) Fluoride: Step-by-Step Calculation
1. Identify Element Counts
Read CrF3 and list how many atoms of each element are present:
- 1 atom of Chromium (Cr)
- 3 atoms of Fluorine (F)
2. Determine Atomic Masses
Look up each element mass from the periodic table:
- Chromium (Cr) ~= 51.996 g/mol
- Fluorine (F) ~= 18.998 g/mol
3. Multiply Atomic Mass by Quantity
Multiply atom count by atomic mass for each element:
- Chromium (Cr): 1 x 51.996 = 52.000 g/mol
- Fluorine (F): 3 x 18.998 = 56.990 g/mol
4. Sum Total Molar Mass
Add all contributions to get the final molar mass in g/mol.
Molar Mass = (1 x 51.996 + 3 x 18.998)
Molar Mass = 52.000 + 56.990
Molar Mass = 108.990 g/mol
Final rounded value shown on this page: 108.99 g/mol.
