J The average kinetic energy of an electron in a ground-state helium atom is 2.4 x 103 kJ/mol.A. What is the corresponding electron velocity using KE = ½ mv2? Remember to convert energy/mol of electrons intoKE/one electron first!B. An experiment is able to measure this velocity with an uncertainty of 10%. Calculate the minimum uncertainty inthe position (∆x) of the electron for this experiment.Hints: First find 10% of the velocity you calculated above (∆v). Then solve ∆x∆v ≥ h/4πm for ∆x. To obtaina minimum, use an = instead of a ≥.C. The effective radius of a helium atom is 130 pm. Is the uncertainty in the position you calculated above a significantfraction of this effective radius? Include a sketch and a calculation in your answer.
