esc An atom of argon has a radius Ir = 71. pm and an average speed in the gas phase at 25°C of 249.m/s. Ar Suppose the speed of an argon atom at 25°C has been measured to within 0.010%. 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 I_ and round it to 2 significant figures. For example, if the smallest box the atom could be in turns r Ar out to be 42.0 times the radius of an atom of argon, you would enter "42.r" as your answer.
