To make this KNOWN solution, 0.1632 g was mixed with water (to the mark) in a 100.mL volumetric flask. The Absorbance of this solution was = 0.901 The Unknown Compound (K2Zy(C2O4)z . nH2O) was used to make another solution: 0.1016 g of the unknown compound was mixed with water (to the mark) in a 100.mL volumetric flask. The Absorbance was = 0.677 1a.) Find the molarity of Z, in the ZSO4 . 3H2O (known) solution.(Z is, again, this fictional metal, with molar mass 87.91 g/mol.)Remember that molarity is moles per liter. 1b.)Find the molarity of Z in the unknown solution using Beer’s Law 1c.)Using your answer, find the moles and then the mass of Z in the unknown solution. 1d.) Find the % Z (by mass) in the unknown compound
