What is molecular mass of potassium in potassium chloride?

Answer 1

Since potassium chloride has the formula KCl and the mass of the lost electron from neutral potassium is negligible compared with the mass of the protons and neutrons in the potassium atom nucleus, the molecular mass of potassium in this compound is the same as the Atomic Mass of potassium, 39.098.

Answer 2

The molecular mass of potassium (K) is approximately 39.1 g/mol, while the molecular mass of chlorine (Cl) is approximately 35.5 g/mol. Therefore, the molecular mass of potassium chloride (KCl) would be around 74.6 g/mol (39.1 + 35.5).

Answer 3

90.55 g/mol or 90.55 amu (atomic mass units)

Answer 4

The relative atomic mass of potassium is 39, and for chlorine it is 35.5. Therefore, the molecular weight of KCl is 74.5 g/mol.

Answer 5

74.551 g/mol

Answer 6

39.09
