Question

For a particular medical procedure, a patient must be injected with

a specific number of nanoparticles. You have a batch of spherical,

solid gold nanoparticles each with a diameter of 33.0 nm. Because

these particles are too small to be weighed individually, you must

calculate the mass one nanoparticle in order to determine the total

weight of material needed for the procedure.

Note: The atomic weight of gold is 196.97 g/mol and the

atomic radius is 0.144 nm. The crystal structure of gold is FCC.

Step 1: (5 min) Write out the steps of a procedure to determine (1)

the mass of one nanoparticle and (2) the approximate number of

atoms each particle contains
