Density = mass / volume
In general, the density of a gas depends on several things: the molecular weight of the gas, the temperature, and the pressure. For an ideal gas, the following equation holds:
P*V = n*R*T
where P is the pressure (in atmospheres, ATM), V is the volume (in liters, L), n is the number of moles, R is the gas constant (R = 0.0820574587 L ATM K-1 mol-1), and T is the temperature (in Kelvin, K).
The density of a gas is the number of grams per volume (usually in g/mL or kg/L). Taking the molar mass (MM) of a substance and multiplying it times the number of moles gives the number of grams. Therefore for an ideal gas, using that fact and rearranging the equation above, we have:
Density = (n*MM)/V = (P*MM)/(R*T)
Make sure your units agree in any and all calculations!
Density is always calculated the same way, whether for solids, liquids, or gases. It is weight divided by volume.
No. Gases have very low density.
The formula for density is?
The chemical formula of gases is dependent on their molecular composition.
No, it isn't.
The density is a physical characteristic, specific for each material, including gases.
As gases are heated up, its volume increases, resulting in a decrease of density.
The formula for density is d= (mass)/(volume)
The noble gases are all monatomic, the formula of the gases is just the atomic symbol, He, Rn.
Yes, every material in the universe has a density.
All materials - including gases - have a density !
I think it is 1g/cm3
Gases have lower densities.
The density of gases depends on temperature and pressure.
Gases, for example
== Density== Mass/ Volume ==
Solids tend to have a higher density because the molecules are arranged closer together where as in gases the molecules are further apart. Since density is Mass/Volume, and solids have more mass per volume than gases it is more dense
The formula of density is mass/volume. So mass divided by volume
Low density: gases Medium density: liquids High density: solids
the change in volume affects the density of solids, liquids , and gases by when the volume of a liquid , solid . or gas expands the density changes.
Gases are compressible, means the density depends on the pressure.
The formula used to determine density is mass divided by volume
density itself is the amount of stuff in an object. The formula is mass divided by volume.
The formula for mass if density is not given is mass=volume/power
