What is the molecular weight of I2KI?
The molecular weight of I2KI (iodine monochloride potassium iodide) can be calculated by adding the atomic weights of its constituent elements: iodine (I) has an atomic weight of approximately 126.9 g/mol, and potassium (K) has an atomic weight of about 39.1 g/mol. In I2KI, there are two iodine atoms and one potassium atom, so the calculation is: (2 × 126.9) + 39.1 = 292.9 g/mol. Therefore, the molecular weight of I2KI is approximately 292.9 g/mol.
