Copper beryllium, also known as beryllium bronze, is a copper alloy with 0.53% beryllium. 3. Given that you already know that a liter of water weighs one kilogram, or 2.2 pounds, you can conclude that the 1 L (1,000 mL) bottle of water you sip your way through during chemistry class would have a mass of: Lead, in comparison, checks in at 11.3 g/cm3, which is very dense, but only about 60 percent of that of gold. Screw the lid back on tightly to avoid spills and leaks. The density of water is roughly 1 gram per milliliter but, this changes with temperature or if there are substances dissolved in it. Mild steel has a relatively low tensile strength, but it is cheap and easy to form; surface hardness can be increased through carburizing. Density can be explained as the relationship between the mass of the substance and the volume it takes up. Gold is thought to have been produced in supernova nucleosynthesis, from the collision of neutron stars. Hassium is a chemical element with symbol Hs and atomic number 108. Why, then, do you suppose that when people talk about unusually dense or heavy things, they so often compare it to lead instead of gold, as in the expression "That joke went over like a lead balloon"? It is also known as marsh gas or methyl hydride. As you can see, rocks of the same type can have a range of densities.
