The molecular weight of Boric acid [H_{3}BO_{3}] is 61.8332.

Boric acid [H_{3}BO_{3}] is an inorganic compound of three elements: Hydrogen, Boron, and Oxygen. The molecular weight of Boric acid is 61.8332 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

**CALCULATION PROCEDURE: Boric Acid [H**_{3}BO_{3}] Molecular Weight Calculation

_{3}BO

_{3}] Molecular Weight Calculation

**Step 1: Find out the chemical formula and determine constituent atoms and their number in a Boric acid molecule.**From the chemical formula, you will know different atoms and their number in a Boric acid molecule. The chemical formula of Boric acid is H

_{3}BO

_{3}. From the chemical formula, you can find that one molecule of Boric acid has three Hydrogen (H) atoms, one Boron (B) atom, and three Oxygen (O) atoms.

**Step 2: Find out the atomic weights of each atom (from the periodic table). **

Atomic weight of Hydrogen (H): 1.008 (Ref: Lanl-1)

Atomic weight of Boron (B): 10.811 (Ref: Jlab-ele005)

Atomic weight of Oxygen (O): 15.9994 (Ref: Jlab-ele008)

**Step 3: Calculate the total weight of each atom present in a Boric acid molecule by multiplying its atomic weight by its number.**

Number of Hydrogen atoms in Boric acid: 3

Atomic weight of Hydrogen: 1.008

Total weight of Hydrogen atoms in Boric acid: 1.008 x 3 = 3.024

Number of Boron atoms in Boric acid: 1

Atomic weight of Boron: 10.811

Total weight of Boron atoms in Boric acid: 10.811 x 1 = 10.811

Number of Oxygen atoms in Boric acid: 3

Atomic weight of Oxygen: 15.9994

Total weight of Oxygen atoms in Boric acid: 15.9994 x 3 = 47.9982

**Step 4: Calculate the molecular weight of Boric acid by adding up the total weight of all atoms. **

Molecular weight of Boric acid: 3.024 (Hydrogen) + 10.811 (Boron) + 47.9982 (Oxygen) = 61.8332

So the molecular weight of Boric acid is 61.8332.
