Calculate the rms velocity of oxygen molecules at S.T.P The molecular weight of oxygen is 32.

Explanation

HereP = 1 atm = `10.13 xx10^5Nm^(-2)`
`M = 32 g = 32 xx10^(-3) kg`
V = Molar volume of S.T.P
= 22.4 litre
`=22.4 xx10^(-3) m^3`
Root mean square velocity of oxygen molecules at S.T.P
`v_(rms)=sqrt((3PV)/M)`
`=sqrt((3xx1.013xx10^5xx22.4xx10^(-3))/(32xx10^(-3)))`
`=461.23 ms^(-1)`
