Best Answer: Basically, density is the amount of mass (molecules/matter) per an area unit. Imagine a box that's half-filled with 15 blue marbles. If that box could be divided into 5 parts and all the parts would have the same number of marbles, you'd get 3 marbles in each box part. That's the density; the number of marbles per box part. Now imagine that same whole box, and you add 5 white marbles. This would be the salt, which would make the water saline.
