A phosphate solution was prepared by diluting 10.00 mL of cola with water to a final volume of 50.00-mL Then 20.00-mL of the diluted cola was added to 5.00 mL of AVM in a clean dry beaker. This new solution was stirred and used to fill the cuvette for data collection. The resulting absorbance was found to be 0.630.
Calculate the concentration of phosphate in the original undiluted cola
