WebSodium chloride / ˌ s oʊ d i ə m ˈ k l ɔːr aɪ d /, commonly known as salt (although sea salt also contains other chemical salts), is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. With molar masses of 22.99 and 35.45 g/mol respectively, 100 g of NaCl contains 39.34 g Na and 60.66 g Cl. Sodium chloride is … WebSep 3, 2024 · Explanation: We (i) take the ration of the mass of the sample to the formula mass of F eCl3 to get the number of moles of F eCl3. 0.072 ⋅ g (55.85 + 3 ×35.46) ⋅ g ⋅ mol−1 = 4.44× 10−4 ⋅ mol. And thus we have a molar quantity with respect to F eCl3 ...the molar quantity with respect to Cl is CLEARLY three times this figure, i.e. 4. ...
