Which monomer is formed when the trimer c9h20o4 is broken down into its monomers?

Belonging to the large family of alcohols, propylene glycol is a chemical element widely used by the food industry thanks to its recognized emulsifying properties. It is referable to its acronym E1520. This colorless, low volatile and soluble diol is also used in many other industries. Pharmaceutical, cosmetic, aeronautic, textile industries ... Propylene glycol is involved in the composition of many polymers such as polyester. Non-toxic when inhaled, propylene glycol is used in electronic cigarette filling fluid to produce an aerosol effect comparable to that of smoke.

With respect to polypropylene glycol, each condensation of propylene glycol causes a loss of a water molecule

C3H8O2 + C3H8O2 + C3H8O2 ==> C9H20O4 + 2H2O

the median of the data is 4.5.

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this
