Homework Statement
A proton, which is the nucleus of a hydrogen atom, can be modeled as a sphere with a diameter of 2.4 fm and a mass of 1.67 multiplied by 10-27 kg. Determine the density of the proton.
Homework Equations
Volume=(4/3)pi*r^3
Density=mass/Volume
The Attempt at a Solution
I first got the radius: 1.2 * 10^-15
To get the volume i did: (4/3)*pi*(radius)^3 and i got 7.2 * 10^-45 as the volume
To get density i just jiust divided 1.67*10^-27/7.2*10^-45
and i got 2.31 *10^17 as the answer which is wrong.
