Question 3 5 pts Gold nanoparticles are typically prepared by the reduction of aurochloric acid (HAUCla) with boiling sodium citrate. The sodium citrate is used in excess and it is assumed that 100% of the Au atoms end up as part of the nanoparticles. If you start with a 1.00% (w/w) aqueous solution of HAC14:3H20 (aurochloric acid is typically available as the trihydrate) and the average particle diameter is 20.0 nm, what is the concentration of Au nanoparticles in the...
