Which is more dense 1 ml of water or 50 l of water?

Answer;

Non is denser than the other, they are the same;

This is because they are both water.

Explanation;

Density is a measure of mass per unit of volume. Density is a measure of mass per volume. The average density of an object equals its total mass divided by its total volume.

Therefore;  if the mass and volume increases the density will be the same. Mass of 1 and volume of 1, 1/1=1.  

Mass of 50 and volume of 50, 50/50=1. (Water density is 1)
