Lamarsh, A. J. Baratta, Introduction to Nuclear Engineering, 3d ed., Prentice-Hall, 2001, ISBN: 0-201-82498-1. There are possibilities for still-higher densities when it comes to quark matter. Nucleus has density 2.310 17 Kg/m 3. Bismuth has been used in solders, a variety of other alloys, metallurgical additives, and medications and in atomic research. The formula for calculating density is p = m/V, where p is the density, m is the mass and V is the volume. The minimum energy required in this regard is called the Nuclear binding force. {\displaystyle R_{0}} = m V where: is the density m is the mass V is the volume The calculation of density is quite straightforward. What is nuclear density formula? Expressed in terms of the mass number A and the atomic number Z for an even-odd nucleus, the Weizsaecker formula is. Typical nuclear radii are of the order 1014 m. Nuclear radii can be calculated according to the following formula assuming spherical shape: r = r 0 .
