A 15.00 g sample containing mixed alkali and other inert components was dissolved and diluted to 300 mL with water. A 20 mL aliquot was titrated with 5.02 mL of 0.5352 M HCl to reach PHP endpoint. Another 20 mL aliquot was titrated to the BCG endpoint, using up 18.87 mL of titrant in the process. Note: Answer in two decimal places only. If there is no answer, type in 0.00. Use the molar masses 105.989 ?/??l ??2cO3 and 84.007 g/mol NaHCO3 indicated. The volume of titrant needed to neutralize NaOH is _________ mL. The volume of titrant needed to neutralize Na2CO3 is _____________ mL. The volume of titrant needed to neutralize NaHCO3 is _____________ mL. The mass of NaOH is ___________ g. The mass of Na2CO3 is __________ g. The mass of NaHCO3 is __________ g. The percent weight of NaOH is __________ %. The percent weight of Na2CO3 is __________ %. The percent weight of NaHCO3 is __________ %.
