One of the student wanted to analyse phosphate ion concentration in Fertilizer industry wastewater sample collected from Rusayl Industrial Estate using spectrophotometer method. She mixed 200.00 mL of wastewater sample which contains only Na,PO. (unknown molarity) with 400.00 mL of 0.0200 M K,PO, in a one liter beaker to make a Solution A. She then transferred 25.00 ml of Solution A to a 250.00 ml volumetric flask and added distilled water up to the calibration mark to make up Solution B. The Concentration of phosphate ions in Solution B is known to contain 3.00 x 10 mol/L from the spectrophotometric analysis at 460 nm using 1 cm cuvette. Calculate the concentration of phosphate ion in wastewater and how many phosphate ions are present in this wastewater.
