How many moles are in 2.58 x 10^24 atoms of calcium?

Use Avagadro’s number. 2.58 x 10^24 atoms x 1 mole/6.022 x 10^23

Explanation:

electron microscopy and scanning tunneling microscopes gives us a greater understanding of atoms by being able to see the atom itself, and lets us see some atomic reactions.

explanation:

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.
