Explanation:
A monomer is defined as the smallest unit that is present in a polymer.
As it is given that chemical formula of monomer is [tex]C_{2}H_{6}O[/tex]. So, when three units of these monomers combine together then it will be [tex]3C_{2}H_{6}O[/tex].
Hence, upon combination of three monomer units of [tex]C_{2}H_{6}O[/tex], the chemical formula of the molecule formed after connecting three of these monomers is [tex]C_{6}H_{18}O_{3}[/tex]
