Computing Molar Mass of Nickel(II) Chromate Step by Step
Molar Mass of Nickel(II) Chromate: Step-by-Step Calculation
1. Identify Element Counts
Read NiCrO4 and list how many atoms of each element are present:
- 1 atom of Nickel (Ni)
- 1 atom of Chromium (Cr)
- 4 atoms of Oxygen (O)
2. Determine Atomic Masses
Look up each element mass from the periodic table:
- Nickel (Ni) ~= 58.693 g/mol
- Chromium (Cr) ~= 51.996 g/mol
- Oxygen (O) ~= 15.999 g/mol
3. Multiply Atomic Mass by Quantity
Multiply atom count by atomic mass for each element:
- Nickel (Ni): 1 x 58.693 = 58.690 g/mol
- Chromium (Cr): 1 x 51.996 = 52.000 g/mol
- Oxygen (O): 4 x 15.999 = 64.000 g/mol
4. Sum Total Molar Mass
Add all contributions to get the final molar mass in g/mol.
Molar Mass = (1 x 58.693 + 1 x 51.996 + 4 x 15.999)
Molar Mass = 58.690 + 52.000 + 64.000
Molar Mass = 174.690 g/mol
Final rounded value shown on this page: 174.69 g/mol.
