Question

The molecules of a certain gas sample at 375 K have a root-mean-square (rms) speed of 271 m/s. Calculate the most probable sp

Answer 1

Answer #1

Vrms = 271m/s

T=375K

Vrms = sqrt(3kT/m) sqrt--square root

Vmp = sqrt(2kT/m). k---boltzmann constant

Vmp = sqrt(2/3)*Vrms. m---mass of a molecule

Vmp = 221.15m/s

m= 3kT/(Vrms*Vrms)

m=3*1.38*10^(-23)*(375)/(271*271)

m=0.02113*10^(-23) kg

Answer 2
