We can use the formula:

M1V1 = M2V2

where M1 is the initial concentration, V1 is the initial volume, M2 is the final concentration, and V2 is the final volume.

Plugging in the given values, we get:

(0.0887 M) x V1 = (0.0224 M) x (275.0 mL)

V1 = (0.0224 M) x (275.0 mL) / (0.0887 M)

V1 = 69.4 mL

Therefore, the answer is D) 69.4 mL.
