please rate my answer and feel free to ask if you have any doubt

o Empirical formulas gt provides the simplest positive . integn rahs of atoms present in that compound moleculor formular at provides the total no of atoms - for a particulor compound. devided by least a 0.50 mal of the imal of a 0.50 mal of oxygen I malf o - Empirical formula = OH Moleculor weight = 34016 gimal Empirical weight = 17.008 gimet. 4 n= molecular weight 1. Empirical weight - 17.000 = 2 Maleculor formula = (Empirical formula) = (04), S . 24.016 ar=h2O2 ec deuid tey least 0.44 mal ofc a mal ofc 0.89 end of the 2.023 mal off 0.45 mol of 1.023 map of o . Empirical formula =CH₂O Moleutor weight = 180-156 gime Empirical weight = 30.026 ginal 180. 156 30:02ī 5 6 moleculor formula = (C1₂O) 18.= colloc a) Empirical formula = Oh maleator formula = 40 6) Empirical fomula = cho Malecular formulas Cotion -
