WebRichard. 2 years ago. "72.06u/72.06u + 12.096u + 96.00u = mass %. 72.06u/180.156u = mass %". Not sure how you arrived at that. Sal begins with the element's relative atomic masses (in u though) and converts them into molar masses. He can do this because the magnitude of an element's relative atomic mass on the periodic table is defined to be ... Web13 jan. 2024 · Triad 1: This triad was constituted by the alkali metals lithium, sodium and potassium. The atomic mass of Sodium = (Atomic Mass of Lithium + Atomic mass of Potassium) / 2. Thus the law of triads is verified for this triad. Triad 2: This triad is comprised of alkaline earth metals i.e. calcium, strontium and barium. cisco final exam 1 to 14 composite answers
