Copper(II) sulfate (CuSO_{4}) is an inorganic compound of three elements: Copper, Sulfur, and Oxygen. The molecular weight of Copper(II) sulfate is 159.6096 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

**CALCULATION PROCEDURE: Copper(II) sulfate [CuSO**_{4}] Molecular Weight Calculation

_{4}] Molecular Weight Calculation

**Step 1: Find out the chemical formula and determine constituent atoms and their number in a Copper(II) sulfate molecule. **You will know different atoms and their number in a Copper(II) sulfate molecule from the chemical formula. The chemical formula of Copper(II) sulfate is CuSO

_{4}. From the chemical formula, you can find that one molecule of Copper(II) sulfate has one Copper (Cu) atom, one Sulfur (S) atom, and four Oxygen (O) atoms.

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

Atomic weight of Copper (Cu): 63.546 (Ref: Jlab-ele029)

Atomic weight of Sulfur (S): 32.066 (Ref: Jlab-ele016)

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

**Step 3: Calculate the molecular weight of Copper(II) sulfate by adding the total weight of all atoms. **

Number of Copper atoms in Copper(II) sulfate: 1

Atomic weight of Copper: 63.546

Total weight of Copper atoms in Copper(II) sulfate: 63.546 x 1 = 63.546

Number of Sulfur (S) atoms in Copper(II) sulfate: 1

Atomic weight of Sulfur: 32.066

Total weight of Sulfur atoms in Copper(II) sulfate: 32.066 x 1 = 32.066

Number of Oxygen (O) atoms in Copper(II) sulfate: 4

Atomic weight of Oxygen: 15.9994

Total weight of Oxygen atoms in Copper(II) sulfate: 15.9994 x 4 = 63.9976

**Step 4: Calculate the molecular weight of Copper(II) sulfate by adding up the total weight of all atoms. **

Molecular weight of Copper(II) sulfate : 63.546 (Copper) + 32.066 (Sulfur) + 63.9976 (Oxygen) = 159.6096

So the molecular weight of Copper(II) sulfate is 159.6096.
