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. 1 atom of Hydrogen (H)
  2. 1 atom of Chlorine (Cl)
  3. 1 atom of Oxygen (O)

2. Determine Atomic Masses

Look up each element mass from the periodic table:

  1. Hydrogen (H) ~= 1.008 g/mol
  2. Chlorine (Cl) ~= 35.450 g/mol
  3. 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.
