Hence, the density of substance is
I think it is polymer B because polymer B has the same structure and the right elements in the right place.
Explanation:
If you use the SI units for P, n, R and T ( In Pa, mol, JK-1mol-1 and K respectively) you'll end up with a Volume with m3 units. So if you have others in different units first convert them into the units I mentioned above and you will definitely get the answer in m3.
