atomic nuclei. Use the mass and size of a nucleon to calculate nuclear density. And once you have nuclear density,use that to find what the weight (in pounds) of a human body would be if it was made entirely of atomic nuclei without all the extra space taken up by the electron clouds. The radius of a nucleon is $1.2\times 10^{-15}$ meters and the volume of an average human is about $0.07m^{3}$ In case you forgot, $1Newton=0.22lbs$ . Please show your full set up , steps, and work for credit.
