Answer:
Explanation:
Recall that the density of a gas is its mass to volume ratio,
ρ
=
m
V
. Therefore, if we can determine the mass of some volume of a gas, we will get its density. The density of an unknown gas can used to determine its molar mass and thereby assist in its identification. The ideal gas law, PV = nRT, provides us with a means of deriving such a mathematical formula to relate the density of a gas to its volume
