A 567.9 mg sample containing Na2CO3, NaHCO3 , NaOH and inert material was dissolved and titrated with 0.1002 M HCl. The titration required 24.30 mL to reach the phenolphthalein endpoint and an additional 38.67 mL to reach the methyl red endpoint. Determine the composition of the sample and the % of each titrated component.

A double indicator analysis of a soda ash sample was performed. The student weighed 0.4375 g of the soda ash sample and dissolved it to make 100.0 mL solution. The students then took a 25 mL aliquot of the sample solution, then added 25 mL H2O and performed double indicator titration. The phenolphthalein endpoint required 10.27 mL 0.04027 M HCl titrant. The sample was further titrated using Methyl Orange and took a total of 15.97 mL of the titrant to reach the endpoint. Given that the molar weight of Na2CO3 - 105.99 g/mol, NaHCO3 = 84.007 g/mol, and NaOH - 39.997 g/mol answer the following: a. What are the components of the soda ash sample?
