The r.m.s. velocity of gas molecules kept at temperature 27^ C in a vessel is 61 ~m / s . Molecular weight of gas is nearly [ R =8.31 ~J ~mol ~K ]

Options

  1. A2
  2. B28
  3. C4
  4. D32

Correct answer

A. 2

Step-by-step solution

Given, array ll & T=27^ C +273=300 ~K & Also, v_ rms =61 ~m / s & ~V _ rms = 3 R T M & M= 3 R T v _ ms ^2 = 3 8.31 300 61 61 =2 array
