Empirical / Molecular FormulasDetermine the empirical formula of thecompounds with the followingcompositions:a. 0.0130 mol C, 0.0390 mol H,and 0.0065 mol Ob. 11.66 g iron and 5.01 g oxygenc. 40 % C, 6.7 % Hand 53.3 % O by massWhat is the molecular formula of each of thefollowing compounds?a. empirical formula CH 2 ,molar mass = 84 g/molb. empirical formula NH 2 Cl,molar mass = 51.5 g/mol
Molecular formula from combustionGiven that the material contains C, H & OBurn 0.225 g of C x H y O zC H O + O(g) → CO(g) + H O(g)x y z2 2 2form 0.209 g H 2 O & 0.512 g CO 21. The number of moles of CO 2 is thenumber of moles of C in C x H y O z2. The number of moles of H 2 O is twice thenumber of moles of H in C x H y O z3. The number of moles of O in C x H y O zmust be determined by difference.
