A standard solution was put through appropriate dilutions to give the concentrationsof iron shown helow. The iron(I1)-1,IO,phenanthroline complex was thenformed in 25.0mL aliquots of these solutions, following whieh each was dilutedto 50.0 mL. The following absorbances (1.00-cm cells) were recorded at510 nm:(a) Plot a calibration eurve from these data.(b) Use the method of least squares to find an equation relating absorbance andthe concentration of iron(II).(c) Calculate the standard deviation of the slope and intercept

August 30, 2016 (Chapter 2, continued) Density Mass d= m o Density= Volume v o Unit for density is g/cm or g/mL. o cm (or cc’s for students going into medicine) is the same as mL. o Finding the density for solid objects: Take a graduated cylinder and fill with water. Place the object into the water gently so that you do not...
