WebThe molar mass of sodium chloride is 58.44 g/mol, which is the sum of the atomic masses of 1 mole of sodium (Na, 22.99 g/mol) and 1 mole of chlorine (Cl, 35.45 g/mol). Two moles of table salt, NaCl, would be twice this amount: m = 2 × 58.44 m = 116.88 g So, the mass of 2 moles of sodium chloride is 116.88 grams. WebSep 20, 2024 · The model in the figure below shows the first four energy levels of an atom. Electrons in energy level I (also called energy level K) have the least amount of energy. As you go farther from the nucleus, electrons at higher levels have more energy, and their energy increases by a fixed, discrete amount.
