Computing Molar Mass of Chromium(III) Acetate Step by Step
Molar Mass of Chromium(III) Acetate: Step-by-Step Calculation
1. Identify Element Counts
Read Cr(C2H3O2)3 and list how many atoms of each element are present:
- 1 atom of Chromium (Cr)
- 6 atoms of Carbon (C)
- 9 atoms of Hydrogen (H)
- 6 atoms of Oxygen (O)
2. Determine Atomic Masses
Look up each element mass from the periodic table:
- Chromium (Cr) ~= 51.996 g/mol
- Carbon (C) ~= 12.011 g/mol
- Hydrogen (H) ~= 1.008 g/mol
- Oxygen (O) ~= 15.999 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
- Carbon (C): 6 x 12.011 = 72.070 g/mol
- Hydrogen (H): 9 x 1.008 = 9.070 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 51.996 + 6 x 12.011 + 9 x 1.008 + 6 x 15.999)
Molar Mass = 52.000 + 72.070 + 9.070 + 95.990
Molar Mass = 229.130 g/mol
Final rounded value shown on this page: 229.13 g/mol.
