just need the things that say pre lab done! i will upvote if it is done!

1. Using solid CuSO45H2O make a "stock" solution of 0.100MCuSO4 in 50mL. Show all calculations in your laboratory notebook and then use the proper solution techniques as demonstrated by your instructor. **If you do not make EXACTLY 0.100M due to mass transfer limitations, then calculate the molarity you did prepare and use that molarity with the volumes calculated in \#2 to prepare your standards and calculate the final molarity. 2. From the stock solution of 0.100M make standards of 0.100,0.0800,0.0500,0.0300,0.0100 CuSO4 in 10ml. Show all calculations in your notebook on how to prepare these and then use proper pipetting technique as demonstrated. 3. Using the spectrophotometer, record absorbance of standards at 650nm. Use Deionized water as the blank. Be sure cuvettes are properly inserted and cleaned of any finger prints. 4. Create a standard curve in Excel with Absorbance vs Concentration CuSO4(M). Record the line equation and R2 value in your notebook and show to instructor. If R2
