Mass number for argon
WebThere are two steps to find the mass of the Argon (Ar) atom. First we find the atomic mass of Ar from the Periodic Table. We then divide this by Avogadro's Number (6.02 x E23). Web30 de oct. de 2016 · Explanation: For potassium metal, Z = 19; its mass is 39.10 ⋅ g ⋅ mol−1. For argon gas, Z = 18; its mass is 39.95 ⋅ g ⋅ mol−1. So even though most argon atoms are more massive than most potassium atoms, all potassium atoms have one more positively charged, massive nuclear particle than does argon.
