Problem PageQuestion An atom of xenon has a radius = and an average speed in the gas phase at of . . Suppose the speed of a xenon atom at has been measured to within . Calculate the smallest possible length of box inside of which the atom could be known to be located with certainty. Write your answer as a multiple of and round it to significant figures. For example, if the smallest box the atom could be in turns out to be times the radius of an atom of xenon, you would enter "" as your answer.
