9. The swelling process is one of the most important properties of macromolecular compounds (HMCs). Determine the degree of swelling of the IUD in the solvent, the density and absorbed volume of which are given in table 9. The table also indicates the mass of the IUD before swelling.

option number m, g v, ml ρ, g/cm3
9 110 42 1.75

When solving the task and preliminary theoretical consideration of the issue, keep in mind that the swelling process is selective and largely depends on the chosen solvent.
