To answer this item, we use the concept of mole balance of nitric acid. It should be noted that there is no nitric acid in the water added. The equation that would best allow us to answer this item is,
                                (0.1015)(20) + 0 = (x)(20 + 250)
The value of x from the equation is 7.52 x 10^-3 m nitric acid.
