a) two 10.0 Ml water samples were taking The procedure in thisexperiment is followed to determine the phosphate concentration.What would be the average phosphate concentration in the solutionbe( in units of molarity) if the student obtained 0.5133g and0.5275g of struvite using gravimetric analysis? show all workassume this procedure precipitates out all of the phosphate fromthe sample in form of struvite. b) what would be the concentrationof the phosphate ion (Po4^3-) in the water sample from the previousquestion (a) in units of parts per millon
