Homework Statement
An iron nucleus has a radius of 5.4x10^-15 and a mass of 9.3x10^-26 what is its mass per unit volume in kg/m^3
Homework Equations
Area of a sphere = 4/3(pi)r^3
Density= M/V
The Attempt at a Solution
i basically plugged everything into the equations so calculated the volume and put it into the density equation but my answer is far to high i think
im getting 1.4x10^17 kgm^-3
just need some clarification on how to complete it or if I am right or not
