Computing Molar Mass of Iodic Acid Step by Step
Molar Mass of Iodic Acid: Step-by-Step Calculation
1. Identify Element Counts
Read HIO3 and list how many atoms of each element are present:
- 1 atom of Hydrogen (H)
- 1 atom of Iodine (I)
- 3 atoms of Oxygen (O)
2. Determine Atomic Masses
Look up each element mass from the periodic table:
- Hydrogen (H) ~= 1.008 g/mol
- Iodine (I) ~= 126.904 g/mol
- Oxygen (O) ~= 15.999 g/mol
3. Multiply Atomic Mass by Quantity
Multiply atom count by atomic mass for each element:
- Hydrogen (H): 1 x 1.008 = 1.010 g/mol
- Iodine (I): 1 x 126.904 = 126.900 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 1.008 + 1 x 126.904 + 3 x 15.999)
Molar Mass = 1.010 + 126.900 + 48.000
Molar Mass = 175.910 g/mol
Final rounded value shown on this page: 175.91 g/mol.

| Element | Count | Mass | Count x mass | Contribution |
|---|---|---|---|---|
| Hydrogen (H) | 1 | 1.008 | 1 x 1.008 | = 1.010 |
| Iodine (I) | 1 | 126.904 | 1 x 126.904 | = 126.900 |
| Oxygen (O) | 3 | 15.999 | 3 x 15.999 | = 48.000 |
Final molar mass 1.010 + 126.900 + 48.000 | = 175.910 | |||
