A piece of copper contains 3.6 x 10^8 atoms. What is the volume of the sample in units of liters?
i have no idea how to start this. Please help thank you!!!

I assume you know the density of copper, and the mass of each atom.
massatom= molmassCu/avagradrosnumber
=\
massallatoms= 3.6E8*massatomabove
volume = massallatoms/densityCu.
if you density of Cu is in grams/cm^3, then you will have to divide the volume by a thousand (1E3) to have it in liters.
massatom= molmassCu/avagradrosnumber
=\
massallatoms= 3.6E8*massatomabove
volume = massallatoms/densityCu.
