Osmium and gold are more dense than Mercury.
See the Related Questions for a complete list of the most dense elements (many of which are more dense than mercury).
Potassium and Lithium
12 cm3 of Mercury is more dense than 7 cm3 of Hydrogen (at the same Temperature and Pressure), so 12 cm3 is more dense than 7 cm3.Whereas 12 cm3 of Hydrogen is less dense than 7 cm3 of Mercury (at the same temperature and pressure), so 7 cm3 is more dense than 12 cm3!Density depends upon the mass of the substance contained in the volume, so given two volumes, no statement can be made about the relative densities of those volumes without any knowledge of the mass of the volumes: density = mass/volume.Knowing the densities of the substances of the volumes, the volume is immaterial as the density is the same - density is the mass per unit volume.
Lead is more dense than feathers. It doesn't matter how much you have of either one. A chip of lead is more dense than a 10-mile convoy of trucks loaded with feathers.
Yes, the weight of the object doesn't matter as much as the density. For example, a pebble will sink in water because it is very dense, yet a log won't because it's not as dense as water.
You're comparing a mass to a volume. A gallon of water can can weigh a certain amount, but a gallon of a more dense fluid can weigh more.
Potassium and Lithium
Yes, there are at least two: Iodine vapor (molar mass 254) and Radon gas (222, but not natural occurring) are heavier (and so more dense) than Mercury vapor (200 g/mol).
Most materials will float in Mercury because it is so dense. A lump of Lead will float in a bath of Mercury. The well-known metals Gold, Platinum, Tungsten, Uranium and Plutonium are more dense than mercury and would sink. More specifically, any material having a density less than 13593 Kg/m3 will float in a bath of Mercury.
Mercury is more dense than silver.
Gold is more dense than mercury
No. Mercury is a liquid metal and is more dense.
Density of our Moon: 3.346 (g/cm3). Density of planet Mercury: 5.427 (g/cm3). So, yes, it is less dense.
Mercury is more dense than iron, causing it to float on the surface of mercury.
guessing mercury
There are several, including gold.
There are many liquids more dense than water. The most commonly thought of is probably Mercury.
Between lead, mercury, gold, and water, mercury is more dense than all the rest. It is type of metal which is most commonly seen and used in its liquid format.
