Computing Molar Mass of Manganese(II) Thiosulfate Step by Step
Molar Mass of Manganese(II) Thiosulfate: Step-by-Step Calculation
1. Identify Element Counts
Read MnS2O3 and list how many atoms of each element are present:
- 1 atom of Manganese (Mn)
- 2 atoms of Sulfur (S)
- 3 atoms of Oxygen (O)
2. Determine Atomic Masses
Look up each element mass from the periodic table:
- Manganese (Mn) ~= 54.938 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:
- Manganese (Mn): 1 x 54.938 = 54.940 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 54.938 + 2 x 32.060 + 3 x 15.999)
Molar Mass = 54.940 + 64.120 + 48.000
Molar Mass = 167.060 g/mol
Final rounded value shown on this page: 167.06 g/mol.
