A sample consisting of Na2CO3 and NaHCO3, and inert matter weighs 6.7447 grams. It is titrated with 0.16 N HCI with phenolphthalein as the indicator, and the solution became colorless after the addition of 22.65 mL. Another duplicate sample was titrated with HCI using methyl orange as indicator. It required 56.94 mL of the acid for the color change. What is the percentage of NaHCO3 (84g/mole) in the sample? (Answers should be written in 2 decimals place and do not include the UNIT)
