Answer
$v_{rms}=1.8\times10^2\frac{m}{s}$
Work Step by Step
Root mean square speed of hydrogen can be calculated from the equation:
$v_{rms}=\sqrt\frac{3RT}{M}$
From Table 19-1, the Hydrogen molar mass is $M=2.0159\times10^{-3}Kg mol^{-1}$
Substituting the values into the equation, we get
$v_{rms}=\sqrt\frac{3(8.314)(2.7)}{2.0159\times10^{-3}}$
$v_{rms}=1.8\times10^2\frac{m}{s}$
