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:
