Using a spectrophotometric technique, the phosphorus content in a mineral will be prolonged. The procedure used is described below: 8.35 g of sample are dissolved and treated so that all phosphorus is converted to the blue orthophosphate complex and made up to volume with distilled water end of 100 ml. The transmission of the resulting solution is 30.6%. If the orthophosphate standard solution of sodium, which is treated in the same way, and which has a final concentration of 2.467x10-4 M, gave a transmittance of 20.5%, calculate the phosphorus content in the driven sample in ppm Na3PO4.
