Unformatted text preview: atom is twice that or 278 pm. A picometer is 1012 meters ( 1 pm = 1012 m). The diameter of the atom in meters is therefore 278 pm 1012 m = 2.78E10 m pm 1.17 mm is 1.17E3 meters. 1.17 mm 103 m = 1.17E3 m mm Dividing the total distance by the distance spanned per atom gives the number of atoms needed: 1.17E3 m atom = 4.21E+6 atoms 2.78E10 m The volume of a single palladium atom is 1.08E23 cm 3 . What is the volume of a palladium atom in microliters? 1.08E20 microliters Feedback: The following conversion factors can be used: 1 L = 1000 cm 3 1 microliter = 106 L Then using dimensional analysis: 1.08E23 cm 3 1 L 1 microliter = 1.08E20 microliters 1000 cm 3 106 L...
