Molecular Mass: The Foundation

Before we delve into the molecular mass of NaCl, it’s essential to understand what molecular mass means. Molecular mass, also known as molecular weight or molar mass, is the mass of a molecule, typically expressed in atomic mass units (u) or unified atomic mass units (AMU). It represents the sum of the atomic masses of all the atoms in a molecule.

Composition of NaCl (Sodium Chloride)

NaCl, or sodium chloride, is a simple ionic compound composed of two elements:

• Sodium (Na) with an atomic mass of approximately 22.98977 u.
• Chlorine (Cl) with an atomic mass of approximately 35.453 u.

Calculating the Molecular Mass of NaCl

To find the molecular mass of sodium chloride, we add the atomic masses of its constituent elements:

Molecular Mass of sodium chloride = (Atomic Mass of Na) + (Atomic Mass of Cl) Molecular Mass of sodium chloride ≈ 22.98977 u + 35.453 u ≈ 58.44277 u

Rounded to four decimal places, the molecular mass of NaCl is approximately 58.4428 atomic mass units (u).
