[[User:Matt Hartings|Matt Hartings]] Moira, keep reading in this reference. There are notes on what to do if the size is less than 32nm. Please complete this analysis. You need to determine the size AND concentration of the nanoparticles along with the concentration of gold (based on your initial concentration and final volume) | [[User:Matt Hartings|Matt Hartings]] Moira, keep reading in this reference.
