What is density?
Density is a physical characteristic, and calculates of mass per unit of volume of a material or substance. It is a measurement of the quantity of matter in a given volume of something.
The higher an object's density, the higher it's mass per unit of volume. The average density of an object equivalent its total mass divided by its total volume. A denser object (like iron) will have less volume than an equal mass of some less dense substance (like water).
A helium nucleus and a neon nucleus are separated by a distance of 3.0 nm. The charge of the helium nucleus is +2e while that of a neon nucleus is + 10e .Find the magnitude of the
