Question

Calculate the rms velocity of oxygen molecule at s. t. p. the molecular weight of oxygen is 32 in physics questions

Answer 1

RMS speed of oxygen molecule is 461.3 m/s.

Answer 2

Dear Student,

◆ Answer -

vrms = 461.4 m/s

● Explanation -

At STP, temperature is 273.15 K.

RMS velocity of oxygen molecule at S.T.P. is -

vrms = √(3RT/M)

vrms = √(3 × 8.314 × 273.15 / 32×10^-3)

vrms = √212903

vrms = 461.4 m/s

Hence, RMS velocity of oxygen molecule at STP is 461.4 m/s.

Thanks dear. Hope this helps you..
