Calculating the molecular mass of Na₂SO₄ is a standard exercise in Class 9 and 10 Chemistry (Atoms and Molecules chapter).
Na₂SO₄ (Sodium Sulphate) is also called Glauber's salt when in its hydrated form Na₂SO₄·10H₂O.
Formula: Na₂SO₄ (Sodium Sulphate)
Atomic masses used:
Count the atoms:
Total = 46 + 32 + 64 = 142 g/mol
The molecular mass of Na₂SO₄ = 142 g/mol
Moles = 284 / 142 = **2 moles**
