Calculate Density of Carbon Atom Nuclear

[omni]

Assume that all the mass of an atom is concentrated in his nuclear it have a Ball-shaped with a radius r=1.5x10^-5pm (1pm=10^-12).

if the mass of a Carbon atom is 2.0x10^3 what is the density of the Carbon nuclear ?

Assume the volume of a ball is 4/3*pi*r^3.


i know we need to use in d=m/v but i don't know exactly how to Convert units from, gr to kg etc.

thnaks.

You have a radius, so you can calculate a volume. Once you have that, you also have a mass, so you can calculate a density.

yea but what about the unit?
