In order to find the concentration of 25 mL NaOH solution, it was titrated against 10000ppm sulfuric acid(Mw=98.08g/mol), 37.5 mL of acid was added to reach the end point. Calculate the molar concentration of sodium hydroxide solution, and then find out the mass of NaOH(Mw=40g/mol) dissolved in 500 mL of this solution
