A student titrated 10.00 ± 0.02 mL of a HNO, (nitric acid) solution with a standardized NaOH (sodium hydroxide) solution (M = 0.1071 mol/L ± 0.0002 mol/L) using a phenolphthalein indicator. It required 12.09 ± 0.04 mL of NaOH to reach the endpoint. Calculate the molarity of the HNO3 solution and associated uncertainty.
