The nucleus of an atom can be modeled as several protons and neutrons closely packed together. Each particle has a mass of 1.67 x 10-27 kg and radius on the order of 10-15 m. (a) Use this model and information to estimate the density of the nucleus of an atom. 3.986E177 Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. kg/m3 (b) Compare your result with the density of a material such as iron. What do your result and comparison suggest about the structure of matter?
