I have looked up multiple definitions and they still seem the same to me. Can anyone help a non-science person wrap my head around the concept?

Best way I can explain it is density is how much of one or more molecules is packed into a certain space – the more tightly its packed, the more dense it is. It’s about mass (weight) and volume (how much space is taken up). Concentration is a ratio. It’s when you want to know how much of molecule A is in mixture B or how many molecules are there per a certain amount. Density is consistent. Molecule A will always have the same density (Density changes when you mix stuff). But concentration can be changed. Like adding salt to water. The more salt, the higher the concentration of salt in the water. The ratio of salt to the combination of salt and water gets bigger. I hope I explained that well, not sure if it was 5 yo level, but I hope it at least helps you a bit.
