Calculate the density of air at 100 deg c and 1 bar abs. use the ideal gas law for your calculation and give answer in kg/m3. use a molecular weight of 28.9 kg/kmol for air. give answer in kg/m3

Explanation:

Using the Ideal Gas Law we have and the number of moles n could be expressed as , where m is the mass and M is the molar mass.

Now, replacing the number of moles in the equation for the ideal gass law:

If we pass the V to divide:

As the density is expressed as , we have:

Solving for the density:

Then we need to convert the units to the S.I.:

Finally we replace the values:
