    A rough estimate of the radius of a nucleus is provided by the formula r kA1/3, where k is approximately 1.3 1013 cm and A is the mass number of the nucleus. Estimate the density of the nucleus of 127I (which has a nuclear mass of 2.1 1022 g) in grams per cubic centimeter. Compare with the density of solid iodine, 4.93 g cm3

    I solved and got 1.80 x 10^14 but that doesn't seem correct.

    It seems like a rather large number when the density of solid Iodine is 4.93 g/cm ^3 :o

    Indeed it does. That would imply that most of solid iodine is empty space, wouldn't it? :)

    Imagine what would happen to an object if all of its nuclei were squished together instead of being surrounded by empty space. Such an object is called a neutron star, and its density is immense.
