Is it necessary to use 0.525 mol/L sodium hydroxide for titrating the acidity of ammonium sulfate?

The laboratory says it’s difficult to prepare standard solutions; is it possible to change the concentration instead?
Generally, for solutions of strong acids and strong bases, a roughly desired concentration is first prepared, and then it is diluted to the exact concentration required; it’s not clear what purpose this intermediate concentration serves.
0.525 mol/L sodium hydroxide solution: prepare by mixing 21 g of sodium hydroxide in approximately 1000 ml of water
