Computing Molar Mass of Nickel(II) Thiosulfate Step by Step
Molar Mass of Nickel(II) Thiosulfate: Step-by-Step Calculation
1. Identify Element Counts
Read NiS2O3 and list how many atoms of each element are present:
- 1 atom of Nickel (Ni)
- 2 atoms of Sulfur (S)
- 3 atoms of Oxygen (O)
2. Determine Atomic Masses
Look up each element mass from the periodic table:
- Nickel (Ni) ~= 58.693 g/mol
- Sulfur (S) ~= 32.060 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
- Sulfur (S): 2 x 32.060 = 64.120 g/mol
- Oxygen (O): 3 x 15.999 = 48.000 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 + 2 x 32.060 + 3 x 15.999)
Molar Mass = 58.690 + 64.120 + 48.000
Molar Mass = 170.810 g/mol
Final rounded value shown on this page: 170.81 g/mol.
