A 10.00 m-L sample of impure ethanol sample was diluted to 1.000 L in a volumetric flask. The ethanol (C2H5OH) in a 25.00-ml aliquot of the diluted solution was distilled into 50.00 mL of 0.02000 M K2Cr207 and oxidized to acetic acid with heating. The reaction is : 3C2H5OH + 2 Cr20-2- + 16H+ 4Cr3+ + 3CH3COOH + 11H20 6 Fe2+ + Cr20-2- + 14H+ +6Fe3+ + 2Cr3+ + 7H20 After cooling, 20.00 mL of 0.1253 M Fe2+ was pipetted into the flask. The excess Fe2+ was then titrated with 7.46 mL of the standard K2Cr2O7 to a diphenylamine sulfonic acid end point. Calculate the percent (w/v) C2H5OH 46.07 g/mol) in the sample. Answer the following questions: i) The no of mmoles of K2Cr207 added to diluted ethanol sample is 1.1492 mmol ii) Total mmoles of iron Il added is 2.506 mmol iii) mmoles of K2Cr2O7 to titrate excess Iron II 0.1492 mmol iv) mmoles of excess Iron II 0.1492 mmol v) mmoles of Iron Il consumed by unreacted K2Cr207 vi) mmoles of K2Cr2O7 equavalent to the mmoles of Iron Il consumed vii) mmoles of K2Cr2O7 reacted with diluted ethanol viii) The no of mmoles of ethanol in 25.00 ml aliquot ix) No of moles of ethanol in original sample solution The no of g of ethanol in original x) solution percent (w/v) of C2H5OH in the xi) sample is (11 marks) Dlease answer all parts of the
