I need help with understanding density. Can you explain it to me?

Which is heavier, water or rock ?
Did you say rock ? Oh yeah ? Are you sure ? When I asked the question, I was thinking of the little rock in my pocket, and a whole swimming pool full of water. So the water is heavier.
That's not fair, is it ! When you were figuring out which one is heavier, you thought about the SAME AMOUNT of each one ... like one bagful, or one jarful.
And that's what 'density' means. It's the amount of mass of a substance, but always the same amount of it. The same amount is always 1 cubic centimeter, and the density is always how many grams of mass there are in that much of it.
That way, you can compare any two substances in the world. When you talk about their densities, you always know that you're talking about the same amount.

Density is the ratio of mass and volume. d= v m ​ To fill the problem imagine that you have 1 liter of water and 1 liter of feathers. For sure 1 liter of water has greater mass. It because water has greater density. In another words, there is more molecule in the same volume.

Density measures how much mass is in a given volume of a substance and is calculated using the formula Density = Mass / Volume. It helps us determine why some objects float or sink in fluids, such as oil and water. Understanding density is useful for comparing materials and their behaviors in practical situations.
