If before Adsorption I had 550 cm3 of NaOH and after adsorption I had 482cm3 of NaOH?

You haven't told us the molarity of NaOH but assuming it is 0.1 mol dm-3 then to find the concentration you can use the following formula:
Amt of substance in mols = volume x concentration
= 482/1000 x 0.1 (we divide vol by 1000 to convert to dm3)
= 0.0482 mols
Concentration = Vol/Mols
= 482/1000 / 0.0482
= 10 mol dm-3
You can shortcut the method but I wanted to show you the proper text book method.
Hope this helps.

The question isn't clear. You had 550 cm3 of NaOH soln. in water? At what concentration? Onto what was it adsorbed?
