Question- you titrated 1740 g of a solid unknown acid that


Question- You titrated 1.740 g of a solid unknown acid that was dissolved in 100.0 mL of distilled water; the initial pH value was 2.5. You found that pH=pKa=4.2 when 12.50 mL of NaOH had been added. The concentration of the sodium hydroxide was 0.500 M.

Part 1) Calculate the initial percent dissociation of the acid sample.(answer= 2.5)

Part 2) Calculate the value of Ka.(answer= 3.2*10^-3)

Part 3) Calculate the molar mass of the acid.(answer= 139)

I need aid for above question. Illustrate each steps for the above problem.
