Find the rms, most probable and average speeds of `SO_2` at `27^@C`.

Explanation

RMS speed ` u_(rms)= sqrt((3RT)/(M ))`
` = sqrt((3 xx 8.314 xx 10^7 xx 300 ) /( 64 ))`
` = 3.42 xx 10^4 cm //sec `
Most probable speed
` u_(mp ) = sqrt((2RT)/(M )) = sqrt((2 xx 8.314 xx 10^7 xx 300 )/( 64 ))`
` = 2.79 xx 10^4 cm // sec `
Average speed
` u_(av) = sqrt(( 8RT)/(pi M ))= sqrt((8 xx 8.314 xx 10^7 xx 300 )/( 3.14 xx 64 ))`
`= 3.15 xx 10^4 cm // sec `
