Answer: 327^0C

Explanation:

The formula used for root mean square speed is:

\nu_{rms}=\sqrt{\frac{3RT}{M}}

where,

\nu_{rms} = root mean square speed

R= gas constant = 8.314J/Kmol

T = temperature = 27^0C=(27+273)K=300K

M = atomic mass of methane = 0.016 kg/mole

Now put all the given values in the above root mean square speed formula, we get:

\nu_{rms}=\sqrt{\frac{3\times 8.314\times 300}{0.016kg/mol}}

for oxygen , \nu_{rms} is same as methane and let temperature is T'

\sqrt{\frac{3\times 8.314\times 300}{0.016kg/mol}}=\sqrt{\frac{3\times 8.314\times T'}{0.032}

T'=600K=(600-273)^0C=327^0C

Thus the RMS velocity of oxygen will be same as that of methane at 27 degree celsius at 327 degree celsius.
