The atomic mass of potassium, K is 39.1. This means that 1 mole of potassium has a mass of 39.1g. Mass of 0.5mol of K = 0.5 x 39.1 = 19.6g
Three pairs of elements that are not ordered by atomic mass are: potassium (K, atomic mass ~39.1) and argon (Ar, atomic mass ~39.9), where potassium comes before argon in the periodic table; cobalt (Co, atomic mass ~58.9) and nickel (Ni, atomic mass ~58.7), where cobalt is placed before nickel; and iodine (I, atomic mass ~126.9) and tellurium (Te, atomic mass ~127.6), where iodine precedes tellurium. These examples highlight instances where the arrangement of elements does not strictly follow increasing atomic mass.
