Please provide a worked out solution.  am particularly confused with what I'm supposed to subtract the total moles of HCl with. I think the concentration of the solution can be determined via M1V1=M2V2 but not sure

A back titration method was used to titrate a sample of a polyeleetrolyte (a
weak base). A 2.056 9 sample of the polyelectrolyte is titrated with 100.0 mi. of
0.1021 M HCl by dissolving the polyelectrolyte in the strong acid solution. The
solution was then filtered and 25.00 mi. of the filtrate was removed and titrated with NaOH. It required 30.45 mi. of 0.04857 M NaOH to reach the equivalence point.
What is the formula weight of the polyelectrolyte in g/mol.
