Homework Statement
What is the Vrms, in meters per second, for helium atoms at 4.8 K? (which is close to the point of liquefaction)
Homework Equations
Vrms= √(3RT)/(M)
The Attempt at a Solution
R=3.145
T= I think its 4.15 Kelvin? based on the point of liquefaction of helium being -269°C
-unsure about the temperature
M= I think its 0.004003 Kg based on the molar mass of helium
Vrms= Sqrt (3*3.1845*4.15)/(0.004003)
Any help would be greatly appreciated, I've tried this a million ways and can't seem to figure it out,
Thank You!
