Given: If you weigh out exactly 0.150 g of an unknown substance to be dissolved in the 100.00 mL volumetric flask, and the concentration of Fe(II) in the 50 mL volumetric flask is calculated to be 1.27 x 10-4 M a. what is the mass (in grams) of iron that you would have in a 100.0 g sample of an unknown substance? HINT GIVEN: You are back calculating from the [Fe(II)] in 50.00 mL to [Fe(II)] in 100.00 mL and then determine the grams of Fe(II) in the mass of unknown sample weighed out to place in the 100 mL flask, to finally be able to calculate the mass of iron in 100.0g of sample.
