if 24.25 mL of a standard M NaOH solution is required to neutralize 26.00 mL of H2SO4, what is the molarity of the acid solution?

You have to know the concentration of the NaOH solution.

Lets say that the NaOH solution is X M.
Number of millimoles of NAOH used is
24.25 x X
each millimole of NaOH neutralises half a millimole of H2SO4
so number of millimoles of H2SO4 is
24.25 x X x 0.5
if C (in mole per litre) is the concentration of H2SO4 then
26.00 x C = 24.24 x X x 0.5
so
C = 24.24 x X x 0.5/26.00
and you can find C when you know X
