A) \[1:\sqrt{2}\]
B) \[\sqrt{2}:1\]
C) \[1:2\]
D) \[2:1\]
Correct Answer: B
Solution :
\[{{V}_{rms}}=\sqrt{\frac{3RT}{M}}\] \[\frac{{{V}_{rms}}\,of\,{{H}_{2}}}{{{V}_{rms}}\,of\,He}=\sqrt{\frac{M\,of\,He}{M\,of\,{{H}_{2}}}}\] \[=\sqrt{\frac{4}{2}}=\frac{\sqrt{2}}{1}\]You need to login to perform this action.
