Data: Listed below are the density values of several materials and/or elements:

Hydrogen: 0.09 g/cm³

Ice at 0ºC: 0.92 g/cm³

Water at 20ºC: 0.998 g/cm³

Water at 4ºC: 1.0000 g/cm³

Krypton: 3.75 g/cm³

Tin: 7.31 g/cm³

Mercury: 13.6 g/cm³

Gold: 19.3 g/cm³

Osmium: 22.6 g/cm³

You: ∞

Me: =You

Conclusion: Density values are fixed for each material. It is what it is. You are what you are. I am what I am. We’ll probably sink to the bottom of the ocean for all we care.
