Understanding its mole weight is fundamental in chemistry as it plays a crucial role in chemical reactions, stoichiometry, and various industrial processes. In this article, we will explore the concept of mole weight, how it is calculated for Na2SO4, and its significance in different applications.

Molecular Weight Of Na2SO4

What is Molecular Weight?

Molecular weight, also known as molar mass, is a fundamental concept in chemistry. It represents the mass of a molecule or compound in atomic mass units (amu). It is calculated by summing the atomic weights of all the constituent atoms in a molecule.

Calculating the Molecular Weight of Na2SO4

To determine the mole weight of Na2SO4, we need to consider the atomic weights of its constituent elements: sodium (Na), sulfur (S), and oxygen (O).

1. Atomic weight of sodium (Na): Approximately 22.99 amu.
2. Atomic weight of sulfur (S): Approximately 32.07 amu.
3. Atomic weight of oxygen (O): Approximately 16.00 amu.

The mole weight of Na2SO4 is calculated by adding up the atomic weights of all the atoms in the compound:

Mole weight of Na2SO4 = (2 * Atomic weight of Na) + Atomic weight of S + (4 * Atomic weight of O)

Mole weight of Na2SO4 = (2 * 22.99 amu) + 32.07 amu + (4 * 16.00 amu)

The Mole weight of Na2SO4 = 45.98 amu + 32.07 amu + 64.00 amu

Mole weight of Na2SO4 = 141.05 amu

The mole weight of sodium sulfate, Na2SO4, is approximately 141.05 atomic mass units.
