Solution: Volume of one mole of ideal gas, Vg​ =22.4 litre =22.4×10−3m3 Radius of hydrogen molecule =1A/2 =0.5A=0.5×10−10m Volume of hydrogen molecule=4/3πr3 =4/3×22/7(0.5×10−10)3m3 =0.5238×10−30m3 One mole contains 6.023×1023 molecules. Volume of one mole of hydrogen, VH =0.5238×10−30×6.023×1023m3=3.1548×10−7m3 Now Vg​/VH​=22.4×10−3/3.1548×10−7=7.1×104 The ratio is very large. This is because the interatomic separation in the gas is very large compared to the size of a hydrogen molecule.Was this solution helpful?150ShareReportAsk your next questionOrUpload the image of your questionGet SolutionOne destination to cover all your homework and assignment needsLearn Practice Revision SucceedInstant 1:1 help, 24x760, 000+ Expert tutorsTextbook solutionsBig idea maths, McGraw-Hill Education etcEssay reviewGet expert feedback on your essaySchedule classesHigh dosage tutoring from Dedicated 3 expertsDownload AppExplore nowTrusted by 4 million+ students
