In this article, we will explore the molecular weight of K2S2O8, its significance, and its applications.

Molecular Formula Breakdown

To calculate the molecular weight of potassium persulfate, we begin by examining its molecular formula. K2S2O8 consists of two potassium (K) atoms, two sulfur (S) atoms, and eight oxygen (O) atoms. The atomic weights of these elements, as derived from the periodic table, are approximately

- Potassium (K) 39.10 g/mol - Sulfur (S) 32.07 g/mol - Oxygen (O) 16.00 g/mol

Now, we can break down the calculations based on the number of atoms in the formula.

Calculation of Molecular Weight

1. Potassium Contribution - K 2 atoms × 39.10 g/mol = 78.20 g/mol

2. Sulfur Contribution - S 2 atoms × 32.07 g/mol = 64.14 g/mol

3. Oxygen Contribution - O 8 atoms × 16.00 g/mol = 128.00 g/mol
