Computing Molar Mass of Silver Sulfite Step by Step
Molar Mass of Silver Sulfite: Step-by-Step Calculation
1. Identify Element Counts
Read Ag2SO3 and list how many atoms of each element are present:
- 2 atoms of Silver (Ag)
- 1 atom of Sulfur (S)
- 3 atoms of Oxygen (O)
2. Determine Atomic Masses
Look up each element mass from the periodic table:
- Silver (Ag) ~= 107.868 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:
- Silver (Ag): 2 x 107.868 = 215.740 g/mol
- Sulfur (S): 1 x 32.060 = 32.060 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 = (2 x 107.868 + 1 x 32.060 + 3 x 15.999)
Molar Mass = 215.740 + 32.060 + 48.000
Molar Mass = 295.790 g/mol
Final rounded value shown on this page: 295.79 g/mol.
