Now that we have a foundational understanding of sodium acetate, let’s dive into the fascinating world of molecular weight and its significance.

Molecular Weight: What Does It Mean?

Molecular weight, also known as molecular mass or molar mass, is a fundamental concept in chemistry. It represents the mass of a molecule expressed in atomic mass units (amu) or unified atomic mass units (u). Molecular weight is essentially a measure of the sum of the atomic masses of all the atoms present in a molecule.

In the case of sodium acetate (NaCH₃COO), its molecular weight is determined by adding up the atomic masses of all the individual atoms that constitute it. This value is not only useful for understanding the compound’s chemical properties but also plays a crucial role in various practical applications.

Calculating the Molecular Weight of Sodium Acetate

To calculate the molecular weight of sodium acetate (NaCH₃COO), we need to consider the atomic masses of its constituent elements:

Now, let’s calculate the molecular mass of sodium acetate:

Molecular Mass of NaCH₃COO = (1 × Atomic mass of Na) + (2 × Atomic mass of C) + (3 × Atomic mass of H) + (2 × Atomic mass of O)

The Molecular Mass of NaCH₃COO = (1 × 22.99 amu) + (2 × 12.01 amu) + (3 × 1.01 amu) + (2 × 16.00 amu)

Molecular Mass of NaCH₃COO ≈ 82.03 amuTherefore, the molecular weight of sodium acetate (NaCH₃COO) is approximately 82.03 atomic mass units (amu).
