2.500 g of an unknown achiral primary amine is dissolved in enough water to yield a 50.00 mL solution. This solution is titrated with 0.9250 M HCl(aq). After 24.95 mL of titrant is added, the pH of the resulting solution is 10.28. After a total of 36.95 mL of titrant is added, the equivalence point is reached. Calculate the molar mass (MM) of the unknown amine.
