Automotive antifreeze consists of ethylene glycol, CH2(OH)CH2(OH), a nonvolatile nonelectrolyte. Calculate the boiling point and freezing point of a 15.0% mass solution of ethylene glycol in water Solution Moles of solute = 1562.07 = 0.2417 mol Mass of solvent = 85 g = 0.085 kg Molality (m) = 0.241 mol0.085 kg = 2.843 m i = 1 (ethylene glycol is a molecular substance and does not dissociate) Kb and Kf of the solvent (water) are constants that are known ΔTb = iKb m = 1.45°C Boiling point of solution = 100 + 1.45 = 101.45°C ΔTf = iKf m = 5.29°C Freezing point of solution = 0 - 5.29 = -5.29°C • Most Viewed Playlist of HomeworkLIB YouTube Channel • 📕 #Economics Q A - https://tinyurl.com/2sb9vdn4 • 📕 #Chemistry Q A - https://tinyurl.com/3r745duk • 📕 #Math Q A - https://tinyurl.com/32ue6d49 • 📕 #Statistics Q A - https://tinyurl.com/4yzhvect • 📕 #Psychology - https://tinyurl.com/46a72y3k • 📕 #Computerscience Q A -https://tinyurl.com/3e52hufx • 📕 #Accounting Q A - https://tinyurl.com/23f5wbha • 📕 #Biology Q A - https://tinyurl.com/yc3xpwwx • 📕 #Physics Q A - https://tinyurl.com/28mmff2c • • #qnawire • #qna • #homework • #mathematics • #science • #history • #literature • #computerscience • #economics • #psychology • #geography • #arts • #AcademicAssignments • #EducationalTasksandProjects • #LearningAssignmentsandExercises • #MathematicalConceptsandTheories • #PrinciplesofMathematicsandItsApplications • #MathematicalProblemSolvingTechniques • #StudyofNaturalPhenomenaandLaws • #ScientificExplorationandInquiry • #EmpiricalInvestigationandAnalysis • #ExplorationofPastEventsandCivilizations • #AnalysisofHistoricalContextsandDevelopment • #UnderstandingtheEvolutionofSocietiesandCultures • #AnalysisandInterpretationofLiteraryWorks • #ExplorationofLiteraryThemesandMotifs • #StudyofLiteraryMovementsandStyles • #UnderstandingComputingTechnology and Systems • #AnalysisofMarketDynamicsandEconomicPolicies • #ExplorationofHumanBehaviorandMentalProcesses • #AnalysisofPsychologicalTheoriesandConstructs • #StudyofMentalHealthandWell-being • #ExaminationofEarth'sPhysicalFeaturesandEnvironments • #AnalysisofHumanGeographyandSpatialRelationships • #UnderstandingGeographicPatternsandProcesses • #ExplorationofArtisticExpressionCreativity • #StudyofVisualandPerformingArtsForms • #AnalysisofCulturalSignificanceandArtisticMovements • #Assignments • #Studytasks • #Academictasks • #Algebra • #Geometry • #Calculus • #Arithmetic • #Trigonometry • #Biology • #Chemistry • #Physics • #Astronomy • #Earthscience • #Worldhistory • #Ancienthistory • #Modernhistory • #Historicalevents • #Civilization • #Fiction • #Poetry • #Prose • #Literaryanalysis • #Literarycriticism • #Programming • #Algorithms • #Datastructures • #Softwareengineering • #Computernetworks • #Microeconomics • #Macroeconomics • #Economictheory • #Marketanalysis • #Economicpolicies • #Behavioralpsychology • #Cognitivepsychology • #Developmentalpsychology • #Clinicalpsychology • #Socialpsychology • #Physicalgeography • #Humangeography • #Cartography • #Geographicinformationsystems(GIS) • #Environmentalgeography • 🎯🎯🎯🎯 • Follow us on Social Media for Latest updates • Instagram - @qna_wire • Facebook - @qna_wire • Twitter - @qna_wire • 👍👍👍👍👍👍👍👍
