Jokes lol you basically do 2000*mm(monomer) but then subtract 2000*mm(H2O) because it forms a condensation polymer

So 2000*131 - 2000*18 (approx molar masses) = 226,000

Condensation polymerisation with one monomer: M(monomer) x n = M(polymer) + (n - 1) x M(water)

Condensation polymerisation with two monomers: (M(monomer 1) + M(monomer 2)) x n = M(polymer) + (2n - 1) x M(water)

Addition polymerisation: M(monomer) x n = M(polymer)
