mass / volumeIf you just want to measure it, all you need is the mass of the gas inside the container and the volume of the container

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!

Why do solids have the highest density and gases have a lower density?

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?
