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.

chakrabortiurbi: 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.

TPS: you want rms velocity of oxygen, right?

chakrabortiurbi: yes but using the density of hydrogen at N.T.P.

chakrabortiurbi: please someone give me the answer of this question

At NTP. temperature = 20 degree celsius = 293.15 K

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