SUMMARY
The root mean square speed (Vrms) of Helium at 5K is calculated using the formula Vrms=sqrt((3kbT)/m). The user initially calculated Vrms as 7.19×10-12 but received an incorrect response. The average kinetic energy (KE) was found to be 1.04×10-22 using the formula 2/3 Kavg/kb, which also returned an incorrect result. The issue was identified as a unit conversion error, specifically converting atomic mass units (amu) to kilograms (kg).
