WebThe formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. How do you find the density of an atom and its nucleus? Density is given by the mass per unit volume. Web16 de abr. de 2012 · Just how small are atoms? And what's inside them?
