The molar mass of KI (Potassium Iodide) is calculated by adding the atomic masses of its constituent elements: Potassium (K) and Iodine (I).
The atomic mass of Potassium (K) is approximately 39.10 g/mol, and the atomic mass of Iodine (I) is approximately 126.90 g/mol.
Therefore, the molar mass of KI is:
39.10 g/mol (K) + 126.90 g/mol (I) = 166.00 g/mol
So, the molar mass of KI is 166.00 grams per mole.
