WebApr 7, 2024 · One mole of sodium = 6.023 × 10 23 a t o m s - But we have to find the number of atoms in 0.2 mole of sodium. - Then, 0.2 mole of sodium = 6.023 × 10 23 a t o m s × 0.2 = 12.046 × 10 23 a t o m s - Therefore 0.2 moles of sodium (Na) contains 12.046 × 10 23 a t o m s in it. Additional information: WebAnswer: “Na” is an element, which means that it’s found on the periodic table. (If you’re studying chemistry you have to have one.) “S” is there as well, so it is an element also. Elemental ionic compounds are the easiest to name because they always end with “-ide.” Here are some examples : ...
