Calculate the root mean square speed of hydrogen in m/s at 27°C?(a) 2835.43 m/s(b) 2635.43 m/s(c) 2735.43 m/s(d) 2731.43 m/sThis question was posed to me in an internship interview.Asked question is from States of Matter topic in portion States of Matter of Chemistry – Class 11

Answer»

Right option is (c) 2735.43 m/s

The explanation: The formula of root mean square speed is given by URMS = \(\sqrt{3RT/M}\). We have R = 8.314 kgm^2/s^2, M = 10^-3 kg/mol and T = 300 k. So by SUBSTITUTING the formula we get, urms = \(\sqrt{3×8.314×300/10^{-3}}\) = 2735.43 m/s.
