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. 1 atom of Hydrogen (H)
  2. 1 atom of Iodine (I)
  3. 3 atoms of Oxygen (O)

2. Determine Atomic Masses

Look up each element mass from the periodic table:

  1. Hydrogen (H) ~= 1.008 g/mol
  2. Iodine (I) ~= 126.904 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
  • 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.

Do You Know?

Iodic Acid contains 3 element types: H, I, O.

I contributes the largest share of this compound's total molar mass.

In HIO₃, O appears with the highest atom count.

Its molar mass is 175.91 g/mol, which is used directly in gram-to-mole conversions.

A common reaction for Iodic Acid is neutralization (HCl + NaOH → NaCl + H₂O).

Why This Compound Matters

Iodic Acid is important in acid-base work, especially when preparing safe measured solutions in lab sessions.

O chemistry is frequently tested in titration and neutralization chapters.

Similar calculations can be compared with Hydroiodic Acid (HI) and Nitric Acid (HNO3).

Where This Is Used

  • Competitive exams and school chemistry tests.
  • Lab work when preparing measured solutions.
  • Real-world manufacturing and quality checks.

Whenever you need lab-ready totals in those settings, molar mass page stays handy for cross-checking.

Common Mistakes When Calculating This

  • Skipping subscripts in HIO₃ and miscounting atoms.
  • Rounding atomic masses too early before finishing all multiplication steps.
  • Mixing up I element contribution with total molar mass.
  • Reporting a value without units; final answer should be in g/mol for Iodic Acid.
