As a result of contamination by atmospheric carbon dioxide, a sodium hydroxide solution contains a small amount of sodium carbonate. To reach the phenolphthalein end point, a 25.00-mL aliquot requires 27.75 mL of 0.1021 M HCl and an additional 1.61 mL to reach the methyl red end point. Calculate the molar concentration of NaOH in the solution.
