The magnesium content of a 100 ml sample of mineral water is analyzed. The Mg2+ in the sample precipitates as MgNH4PO4 and this precipitate is transformed into Mg2P2O7, weighing 0.05 g. a) Obtain the [Mg2+] in the sample. (b) Express in parts per million (that is, in grams of Mg per million grams of water) the amount of magnesium in the sample.
