A sample of tris(hyroxymethyl) aminomethane (H2NC(CH2OH)3), which is a base, with a mass of 0.5875 g is dissolved in water as well as used to standardize a solution of hydrobromic acid. An endpoint is reached when 34.63mL of hydrobromic acid has been added. Find out the molarity (in mol/L) of the hydrobromic acid solution.
