mass of copper = 2.494g; Wavelength = 830.6 Volume of volumetric flask - 50 ml Here's the absorbance of all the test tube XCALCULATIONSUse your recorded weight of copper(II) sulfate pentahydrate to calculate the exactconcentration of your stock copper(II) sulfate solution in the volumetric flask. Use theconcentration of the stock solution to calculate the copper(II) sulfate concentration ofeach sample and summarize this data in an appropriate table, such as:Copper(II)Sample # Concentration, mol/Liter12345(M)→AbsorbanceUsing a program such as Microsoft Excel® or Goggle Sheets, plot the absorbance (y-axis) at the absorption maximum (near 816 nm) versus the known concentration ofcopper (II) ion (x-axis) for samples 1-5.

For example, CHCIBII is chiral, but CCl,BrI is achiral because some of the bonded groups are the same. If a chiral carbon atom is present, then that molecule has a non-superimposable mirror image called an enantiomer. (Figure 1) Part A Identify all the chiral atoms in the below structure by right-clicking* a chiral atom to bring up a menu that includes "Atom Properties."
