A student is performing a titration experiment to determine the concentration of a Nitric Acid (HNO3). The student prepares a 10.0 mL sample of HNO3 with phenolphthalein and prepares to titrate with 2.71 M Potassium Hydroxide (KOH) The initial volume of the buret reads 6.35 mL. KOH is added to the sample until a faint pink color is present; the final volume of the buret reads 15.10 mL. Calculate the

Question
A student is performing a titration experiment to determine the concentration of a Nitric Acid (HNO3). The student prepares a 10.0 mL sample of HNO3 with phenolphthalein and prepares to titrate with 2.71 M Potassium Hydroxide (KOH) The initial volume of the buret reads 6.35 mL. KOH is added to the sample until a faint pink color is present; the final volume of the buret reads 15.10 mL. Calculate the concentration of the HNO3 in this sample.

The same procedure from above is repeated to calculate an accurate concentration of the sample. The same volume of the HNO3 sample is prepared and is titrated with 2.71 M KOH. The initial volume of the buret reads 15.10 mL, and after titrating the sample the final volume reads 23.00 mL. Calculate the concentration of the HNO3 in this sample.
