Computing Molar Mass of Hypochlorous Acid Step by Step
Molar Mass of Hypochlorous Acid: Step-by-Step Calculation
1. Identify Element Counts
Read HClO and list how many atoms of each element are present:
- 1 atom of Hydrogen (H)
- 1 atom of Chlorine (Cl)
- 1 atom of Oxygen (O)
2. Determine Atomic Masses
Look up each element mass from the periodic table:
- Hydrogen (H) ~= 1.008 g/mol
- Chlorine (Cl) ~= 35.450 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
- Chlorine (Cl): 1 x 35.450 = 35.450 g/mol
- Oxygen (O): 1 x 15.999 = 16.000 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 35.450 + 1 x 15.999)
Molar Mass = 1.010 + 35.450 + 16.000
Molar Mass = 52.460 g/mol
Final rounded value shown on this page: 52.46 g/mol.

| Element | Count | Mass | Count x mass | Contribution |
|---|---|---|---|---|
| Hydrogen (H) | 1 | 1.008 | 1 x 1.008 | = 1.010 |
| Chlorine (Cl) | 1 | 35.450 | 1 x 35.450 | = 35.450 |
| Oxygen (O) | 1 | 15.999 | 1 x 15.999 | = 16.000 |
