Answer:
Density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. ... For example, the density of air is 1.2 kilograms per cubic metre.

Answer:
Density is defined as mass per unit volume.
If you happen to know how much gas you have and its volume, the calculation is easy. Usually, you only have implied information and need to use the ideal gas law to find the missing bits.
The ideal gas law is PV = nRT, so if you know enough values, you can calculate volume (V) or the number of moles (n). Sometimes you then have to convert number of moles to grams.
The ideal gas law may be used to approximate the behavior of real gases, but there is always a bit of error in the result.
