What is Khp Molecular Weight?

The Khp Molecular Weight refers to the sum of the atomic weights of all the atoms in a molecule of potassium hydrogen phosphate. The molecular weight is calculated by adding the atomic weights of potassium (K), hydrogen (H), phosphorus (P), and oxygen (O) in the compound. The formula for potassium hydrogen phosphate is K₂HPO₄, which means it contains two potassium atoms, one hydrogen atom, one phosphorus atom, and four oxygen atoms.

Calculating the Khp Molecular Weight

To calculate the Khp Molecular Weight, you need to know the atomic weights of each element involved:

Potassium (K): 39.10 g/mol
Hydrogen (H): 1.01 g/mol
Phosphorus (P): 30.97 g/mol
Oxygen (O): 16.00 g/mol

The calculation is as follows:

Molecular Weight of K₂HPO₄ = (2 × Atomic Weight of K) + (1 × Atomic Weight of H) + (1 × Atomic Weight of P) + (4 × Atomic Weight of O)

Molecular Weight of K₂HPO₄ = (2 × 39.10) + (1 × 1.01) + (1 × 30.97) + (4 × 16.00)

Molecular Weight of K₂HPO₄ = 78.20 + 1.01 + 30.97 + 64.00

Molecular Weight of K₂HPO₄ = 174.18 g/mol

Therefore, the Khp Molecular Weight is approximately 174.18 grams per mole.
