What is the density for carbon?

Answer 1

In the gas phase (which is how it exist at room temperature and standard pressure), it will depend on the temperature and pressure.

See the Related Questions link about the Ideal Gas Law (the density is grams per volume, which can be found from moles per liter if you then use the molar mass to convert moles to grams).

Answer 2

A gram-mole of any gas occupies 22.4 litres. The molecular weight of CO2 is one of carbon plus two of oxygen, 1 x 12 + 2 x 16, in other words 44.

That means that a gram-mole of CO2 is 44 grams, which occupies 22.4 litres or 22,400 cc, so its density is 44/22400 or 0.00196 gm/cc.

The MW of hydrogen is 2, nitrogen is 18, oxygen is 32, so CO2 is a relatively dense gas.

Answer 3

At 0° C, one mole of carbon dioxide gas has a mass of 44 g and a volume of 22.4 liters. If you then convert the temperatures to Kelvin, 0°C becomes 273 K and room temperature becomes 298 K.

Changing the temperature does not change the mass, but it does change the volume.

V/T = V/T

22.4 L/273 K = x/293 K; x = 24.04 L

Answer 4

Carbon dioxide's density is 1600kg/m3 when solid and 1.98 kg/m3 at standard temperature and pressure in its gaseous form.

Answer 5

Carbon (in its elemental form) comes in two forms: diamond and graphite.

Graphite is the more common form and has a density of 2.267 g/mL.

Diamond has a density of 3.515 g/mL.

Answer 6

i do not know i said you should answer it.....ahh nyways nice known u cn also answer here.! its soo kul way beta den daome oda crappy sitess..!!
