Chapter 2, Problem 104E

One of the particles in an atom is the proton. A proton has a radius of approximately $1.0\times {10}^{13}$ cm and a mass of $1.7\times {10}^{24}$

g. Determine the density of a proton. (Hint: Find the volume of the proton and then divide the mass by the volume to get the density.)

$\left(\text{volume of sphere}=\frac{\text{4}}{\text{3}}{\text{πr}}^{\text{3}}\text{;π=3}\text{.14}\right)$
