QUESTION 1 The company gave Phereseadula, who is an analyst, 5.00 L of H3PO4 and he was required to calculate its concentration in mol/L. He called this solution P. He transferred 15.0 mL of solution P with a pipette into an empty 250.0 mL volumetric flask to form solution Q. He added distilled water to the graduation mark of this flask and mixed the content of this flask well. The analyst transfer 20.0 mL of solution Q with a pipette into an empty conical flask and added an indicator to this solution. The content of the conical flask was titrated with 0.4051mol/L sodium hydroxide solution (solution R). If at the endpoint of the titration, the reading on the burette was 22.22 mL; show all the steps he followed to calculate the required concentration.
