The molecular weight of Sodium molybdate (Na₂MoO₄) is 205.92713856.

Sodium molybdate (Na₂MoO₄) is an inorganic compound of three elements: Sodium, Molybdenum, and Oxygen. The molecular weight of Sodium molybdate is 205.92713856 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

CALCULATION PROCEDURE: Sodium molybdate [Na₂MoO₄] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Sodium molybdate molecule.
You will know different atoms and their number in a Sodium molybdate molecule from the chemical formula. The chemical formula of Sodium molybdate is Na₂MoO₄. From the chemical formula, you can find that one molecule of Sodium molybdate has two Sodium (Na) atoms, one Molybdenum (Mo) atom, and four Oxygen (O) atoms.

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 Molybdenum (Mo): 95.95 (Ref: Jlab-ele042)
Atomic weight of Oxygen (O): 15.9994 (Ref: Jlab-ele008)

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

Number of Sodium atoms in Sodium molybdate: 2
Atomic weight of Sodium: 22.98976928
Total weight of Sodium atoms in Sodium molybdate: 22.98976928 x 2 = 45.97953856

Number of Molybdenum (Mo) atoms in Sodium molybdate: 1
Atomic weight of Molybdenum: 95.95
Total weight of Molybdenum atoms in Sodium molybdate: 95.95 x 1 = 95.95

Number of Oxygen (O) atoms in Sodium molybdate: 4
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Sodium molybdate: 15.9994 x 4 = 63.9976

Step 4: Calculate the molecular weight of Sodium molybdate by adding up the total weight of all atoms.

Molecular weight of Sodium molybdate : 45.97953856 (Sodium) + 95.95 (Molybdenum) + 63.9976 (Oxygen) = 205.92713856

So the molecular weight of Sodium molybdate is 205.92713856.
