What do you think makes one liquid more dense than another?

I'm trying to find a liquid that I havent yet identified (color green) with a density of 1.0028 g/mL. The second liquid is (color blue) with a density of 0.7576 g/mL, which I think is Ethyl Alcohol. The densities are not rounded because it is from my lab activity, but they are rounded according to my science textbook. One more thing, can someone help me find the liquid substance with 1.0028 g/mL density that is color green?

Density is defined as mass per unit volume (D=m/v). The standard against which liquid densities are compared is of course water, with a density of about 1 g/ml.  Something more dense than water has more of its molecules (mass) packed into a given space (volume); something less dense is just the opposite, having a lesser number of molecules in a given space.  Since by experiment, you've got an unknown liquid with a density 1.0028 g/ml, round the number to 1.003 and compare with known values in your textbook.

It is based on the formula, which is density= mass over volume. The denser the liquid, the more number of molecules that is closely packed together in a given volume of area. Round the number close to three significant figures and try finding values that would fit the unknown liquid data.

Water with a few drops of green food-colouring agent?

It's worth a shot.

The density of water is 1.00 g/ml

Your green liquid is 1.0028 g/ml.

That is almost exactly the same as water, so I suspect it is "Mostly water with something green in it" !!! Maybe some sort of green water-based drink ??? Something like that.
