The density of hydrogen at N.T.P.is 8.96x10^(-5) g/c.c.Calculate the root mean square velocity for an oxygen molecule at N.T.P.
you want rms velocity of oxygen, right?
yes but using the density of hydrogen at N.T.P.
please someone give me the answer of this question

At NTP. temperature = 20 degree celsius = 293.15 K

V_r_m_s= \sqrt{ \frac{3RT}{M} } =\sqrt{ \frac{3*8.314*293.15}{0.032} } =478\ m/s
