Answer:
Explanation:
Hello,
Considering the ideal equation of state:
The moles are defined in terms of mass as follows:
Whereas the gas' molar mass, thus:
Now, since the density is defined as the quotient between the mass and the volume, we get:
Solving for :
Thus, the result is given by:
Best regards.
