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

sample of 
solution of unknown concentration. To determine the concentration, we divide the sample into three 
samples and titrate each sample separately with 
. Each sample is titrated completely and the titration data is shown below.
