Consider the reaction of $0\mathrm{.}6$mol pentanedioic acid, $0\mathrm{.}4$mol ethylene glycol, and $0\mathrm{.}1$mol erythritol in $1L$ solvent. Using both Carother's theory and Flory statistical theory, predict the extent of reaction at which the polymer will form an infinite network $($or gel$).$
