sorry, i'm having trouble grasping a lot of this... i feel like i have a general understanding of what's going on but a lot of the problems are still confusing to me...(adsbygoogle = window.adsbygoogle || []).push({});

this problem

An element in its solid phase has mass density 1750 kg/m3 and number density 4.39 * 10^28 atoms/m3.

asks what is the element's atomic mass number

i thought that it should just be 4.39*10^28 divided by 1.661 *10^-27 = u, but then i'm not sure where the mass in kg comes in to play
