The diameter of a poker chip is approximately 39 millimeters (mm). An atom of silver (Ag) is approximately 320. picometers (pm) in diameter. Calculate the number of silver atoms needed to span the diameter of a poker chip in a line. Express your answer in scientific notation, showing the correct number of significant figures. (1 m = 103 mm = 1012 pm)
(a) Write the given quantities and specify what needs to be found. diameter of each poker chip = _____ mm (b) diameter of each Ag atom = ____ pm We need to determine the number of Ag atoms that would span the diameter of a poker chip.
