Understanding the Molecular Weight of Potassium Persulfate (K2S2O8)

Potassium persulfate, with the chemical formula K2S2O8, is an important inorganic compound widely utilized in various industrial applications. Its significance stems not merely from its reactivity but also from its unique properties, one of which is its molecular weight. Understanding the molecular weight of potassium persulfate is crucial for chemists and industrial practitioners alike, as it assists in calculations necessary for utilizing this compound effectively in different processes.

The molecular weight of potassium persulfate can be calculated by summing the atomic weights of its constituent elements—potassium (K), sulfur (S), and oxygen (O). According to the periodic table, the atomic weights are approximately 39.10 g/mol for potassium, 32.07 g/mol for sulfur, and 16.00 g/mol for oxygen. In potassium persulfate, there are two potassium atoms, two sulfur atoms, and eight oxygen atoms.

To calculate the molecular weight of K2S2O8, we use the following formula

\[ \text{Molecular weight} = 2 \times \text{(Atomic weight of K)} + 2 \times \text{(Atomic weight of S)} + 8 \times \text{(Atomic weight of O)} \]

Substituting in the atomic weights, we have

\[ \text{Molecular weight} = 2 \times 39.10 \, \text{g/mol} + 2 \times 32.07 \, \text{g/mol} + 8 \times 16.00 \, \text{g/mol} \]

Calculating each term gives

\[ = 78.20 \, \text{g/mol} + 64.14 \, \text{g/mol} + 128.00 \, \text{g/mol} \]
