rxrO2=√MO2Mx=⟮45⟯2=32Mx⇒Mx=50
dx=0.80kgm−3
Vm=1000800×50=62.5L
Z=PVmRT=1×62.50.0821×500=1.52
Explanation:-
Answer: Option D. -> The mean translational kinetic energy of the molecules is proportional to the absolute temperature:
D
All molecules of an ideal gas show random motion. They collide with each other and walls of container during which they lose or gain energy so they may not have same kinetic energy always.
Explanation:-
Answer: Option C. -> 0.96 atm:
C
Pressure ofO2(dry) = 751 - 21 = 730 mm Hg = 730760= 0.96 atm
