Answer;
Non is denser than the other, they are the same;
This is because they are both water.
Step-by-step 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)
