What is the potassium content of potassium sulfate (K2SO4)?

To determine the potassium content of potassium sulfate (K2SO4), one must consider the molecular weight and the composition of the compound. Potassium sulfate consists of two potassium (K) atoms, one sulfur (S) atom, and four oxygen (O) atoms.

1. The atomic weight of potassium is approximately 39.1 grams/mol.

2. The atomic weight of sulfur is about 32.1 grams/mol.

3. The atomic weight of oxygen is approximately 16.0 grams/mol.

The molar mass of potassium sulfate can be calculated as follows:

• Potassium: 2 x 39.1 g/mol = 78.2 g/mol

• Sulfur: 1 x 32.1 g/mol = 32.1 g/mol

• Oxygen: 4 x 16.0 g/mol = 64.0 g/mol

Adding these together gives:

78.2 g/mol (K) + 32.1 g/mol (S) + 64.0 g/mol (O) = 174.3 g/mol (total for K2SO4).

To find the potassium content percentage, divide the total weight of potassium by the total weight of the compound:
