LARN 130 C33D2 Start the following in class: 1.a. The required focus topic, J130A, for today is: You have a job as a laboratory technician.  Describe what must be done to prepare 175.0 mL of a 0.250 M CuSO4 aqueous solution. You will need to use the copper (II ) sulfate pentahydrate, CuSO4•5H2O(s), found in the stockroom to prepare the solution.  Describe what size volumetric flask that you would use and explain the reason for your selection. Show the calculation of the number of moles of CuSO4•5H2O(s) that must be measured into the volumetric flask that you selected to use.  Label all units and show cancellation of units for this calculation. Show the calculation of the number of grams of CuSO4•5H2O(s) that must be measured into the volumetric flask that you selected to use.  Label all units and show cancellation of units for this calculation. Describe the steps needed to prepare the 0.250 M  CuSO4(aq) solution starting with the quantitative transfer of the calculated...
