The rms (root-mean-square) speed of a diatomic hydrogen molecule at 50∘C is 2000 m/s. Note that 1.0 mol of diatomic hydrogen at 50∘C has a total translational kinetic energy of 4000 J. Part A Diatomic oxygen has a molar mass 16 times that of diatomic hydrogen. The root-mean-square speed vrms for diatomic oxygen at 50∘C is: Choose the correct value of vrms. View Available Hint(s) Choose the correct value of . (16)(2000m/s)=32000m/s (4)(2000m/s)=8000m/s 2000m/s (14)(2000m/s)=500m/s (116)(2000m/s)=125m/s none of the above Part B The total translational kinetic energy of 1.0 mole of diatomic oxygen at 50∘C is: Choose the correct total translational kinetic energy. View Available Hint(s) Choose the correct total translational kinetic energy. (16)(4000J)=64000J (4)(4000J)=16000J 4000J (14)(4000J)=1000J (116)(4000J)=150J none of the above Part C The temperature of the diatomic hydrogen gas sample is increased to 100∘C. The root-mean-square speed vrms for diatomic hydrogen at 100∘C is: Choose the correct vrms. Choose the correct . (2)(2000m/s)=4000m/s (2–√)(2000m/s)=2800m/s 2000m/s (12–√)(2000m/s)=1400m/s (12)(2000m/s)=1000m/s none of the above
