The molecular weight of Sodium fluoride (NaF) is 41.988172443.

Sodium fluoride (NaF) is an inorganic compound of two elements: Sodium, and Fluorine. The molecular weight of Sodium fluoride is 41.988172443 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

**CALCULATION PROCEDURE: Sodium Fluoride (NaF) Molecular Weight Calculation**

**Step 1: Find out the chemical formula and determine constituent atoms and their number in a Sodium fluoride molecule.**You will know different atoms and their number in a Sodium fluoride molecule from the chemical formula. The chemical formula of Sodium fluoride is NaF. From the chemical formula, you can find that one molecule of Sodium fluoride has one Sodium (Na) atom and one Fluorine (F) atom.

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

Atomic weight of Sodium (Na): 22.98976928 (Ref: Ciaaw-sodium)

Atomic weight of fluorine (F): 18.998403163 (Ref: Pubchem-9, Ciaaw-fluorine)

**Step 3: Calculate the molecular weight of Sodium fluoride by adding the total weight of all atoms.**

Number of Sodium (Na) atoms in Sodium fluoride: 1

Atomic weight of Sodium: 22.98976928

Total weight of Sodium atoms in Sodium fluoride: 22.98976928

Number of Fluorine (F) atoms in Sodium fluoride: 1

Atomic weight of Fluorine: 18.998403163

Total weight of Fluorine atoms in Sodium fluoride: 18.998403163

**Step 4: Calculate the molecular weight of Sodium fluoride by adding the total atomic weight of all atoms. **

Molecular weight of Sodium fluoride (NaF): 22.98976928 (Sodium) + 18.998403163 (Fluorine) = 41.988172443

So the molecular weight of Sodium fluoride is 41.988172443.
