One method used commercially to peel potatoes is to soak them in a solution of NaOH for a short time, remove them from the NaOH, and spray off the peel. The concentration of NaOH is normally in the range 3 to 6 M. The NaOH is analyzed periodically. In one such analysis, 45.7 mL of 0.500 M H2SO4 is required to react completely with a 20.0 Ml sample of the NaOH solution. What is the molar concentration of the NaOH solution? Select one:   a. 3.87 M   b. 4.78 M   c. 1.00 M   d. 2.28 M
