Understanding the Molecular Weight of Potassium Persulfate (K2S2O8) Potassium persulfate, with the chemical formula K2S2O8, is an inorganic compound commonly used in various industrial and laboratory applications. It is a white crystalline solid that plays a significant role as a strong oxidizing agent. In this article, we will delve into the significance of its molecular weight, its applications, and its properties. Molecular Weight Calculation To comprehend the molecular weight of potassium persulfate, we first need to analyze its chemical composition - Potassium (K) The atomic weight of potassium is approximately 39. 10 g/mol . Since there are two potassium atoms in the formula K2S2O8, their contribution to the molecular weight is \[ 2 \times 39.10 = 78.20 \, \text{ g/mol} \] - Sulfur (S) The atomic weight of sulfur is about 32.07 g/mol. With two sulfur atoms, the total from sulfur is \[ 2 \times 32.07 = 64.14 \, \text{ g/mol} \] - Oxygen (O) The atomic weight of oxygen is roughly 16.00 g/mol. With eight oxygen atoms in the formula, this part contributes \[ 8 \times 16.00 = 128.00 \, \text{ g/mol} \] Now, we can sum these contributions to find the total molecular weight of potassium persulfate \[ Molecular \, Weight = 78.20 + 64.14 + 128.00 = 270.34 \, \text{ g/mol} \] Thus, the molecular weight of potassium persulfate (K2S2O8) is approximately 270.34 g/mol. This information is pivotal for chemists and professionals in industries that utilize this potent compound.
