What is the theoretical density of iron?
7.87 g/cm3
How do you calculate theoretical density?
It is easy to calculate the true density from the molecular weight and the unit cell volume. If the unitcell has more than one formula unit you have to multiply it with the formula weight and divide by the unitcell you will get the true density also called as X-ray density of materials.
How do you find the density of water?
The mass and size of the molecules in a liquid and how closely they are packed together determine the density of the liquid. Just like a solid, the density of a liquid equals the mass of the liquid divided by its volume; D = m/v. The density of water is 1 gram per cubic centimeter.
Is the density of iron greater than gold?
Gold has many more protons and neutrons in the nucleus of each atom than iron does. So each gold atom weighs almost four times as much as each iron atom. So gold ends up denser.
Is gold heavier than steel?
Gold is denser than steel. Density of gold is 19.3 gm/cc and that of copper is 8.9gm/cc.
What material is more dense than iron?
aluminum
Which is stronger iron or gold?
Gold is denser than steel. Iron is, even when totally unalloyed and unworked, far stronger than gold.
Why is gold so weak in Minecraft?

What is the rarest material in the universe?

What is the rarest planet?
Known as GW Orionis (or GW Ori) and located about 1,300 light-years from Earth, the system is a rare example of a triple-star solar system, with two suns orbiting one another at the center, and a third star swirling around its siblings from several hundred million miles away.
What is the rarest star?
An O-type star is a hot, blue-white star of spectral type O in the Yerkes classification system employed by astronomers.
What is the hottest star in the universe?
But the hottest known stars in the Universe are the blue hypergiant stars. These are stars with more than 100 times the mass of the Sun. One of the best known examples is Eta Carinae, located about 7,500 light-years from the Sun.
What type of visible star is the coolest?
- A red dwarf is the smallest and coolest kind of star on the main sequence.
- The coolest red dwarfs near the Sun have a surface temperature of ~2,000 K and the smallest have radii of ~9% that of the Sun, with masses about ~7.5% that of the Sun.
