Number of moles of Fe = Given mass of Fe / Molecular mass of Fe. Number of moles of Fe = 7.85 g / 56 g = 0.1402. Ans: Number of moles of Fe = 0.1402. 7.9 mg of Ca (at. mass 40) Given mass of Ca =7.9 mg = 7.9 × 10-3 g. Ca is a monoatomic molecule. Hence molecular mass of Ca = …
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 ...
