nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.
Answer from: Quest
the density of gold = 19.3 g/cm3
the relation between density and mass and volume is
density = mass / volume
given :
mass of gold = 13 g
density = 13g / volume = 19.3
volume = 13 /19.3 = 0.67 cm^3
thus volume of gold nugget = 0.67 cm^3
