Finding the empirical formula of iron oxide? SocraticNov 20, 2015 · For oxygen, you will have. 32.72g 1 mole O 16.0g = 2.045 moles O. To determine the empirical formula of the iron oxide, you need to find the smallest whole number ratio that exists between the two elements in the compound. To do that ,divide both values by the smallest one. For Fe:1.534moles 1.534moles = 1. For O:2.045moles 1.534moles = 1
Chapter 3. Stoichiometry:MoleMass Relationships in % C, 6.71 mass % H, and 53.3 mass % O. (a) Determine the empirical formula of lactic acid. (b) Determine the molecular formula. 20 Plan:Assume 100 g lactic acid to e each mass % as grams. Convert grams to moles and find the empirical formula. Solution:E mass % as grams; assume 100 g lactic acid:Similarly, there are 6.71 g H and
Determining Empirical and Molecular Formulas ChemistryThe CtoN and HtoN molar ratios are adequately close to whole numbers, and so the empirical formula is C 5 H 7 N. The empirical formula mass for this compound is therefore 81.13 amu/formula unit, or 81.13 g/mol formula unit. We calculate the molar mass for nicotine from the given mass and molar amount of compound:
