(Density=mass/volume)Find the reference value of a 10% salt solution and calculate % error.PROCEDURE B:Preparation of 50.0 ml of 1.0 M CuSO4.Calculate the amount of CuSO4 needed to make 50.0 ml of 1.00 M solution. CuSO4(5H20) molecular weight = 250 g/moleTare a small beaker. Do not remove it from the balance.Slowly pour CuSO, into the beaker until balance reads the correct weight.Dissolve the weighed CuSO4 in 25-30 ml of distilled water.Transfer to a volumetric flask through a funnel. If vou spill any, you must start again.1.2.Rinse the funnel into the flask with a stream of distilled water.Add distilled water to the mark. Add the last few drops water carefully with a dropper.Use this standard solution to prepare more dilute solutions of CuSO, in procedure C.7.PROCEDURE C:Preparation of more dilute solutions of CuSO41.Calculate the size of the aliquot needed to prepare 50.0 ml of 0.50 M CuSO4 solutionfrom your standard solution.Pour a small amount of your standard solution to a small beaker and pipet the calculatedaliquot from the beaker to a clean 50 ml volumetric flask. Dilute to volume.2.3.Stopper the flask, invert and swirl.Repeat the above steps to prepare 0.25 M and 0.10 M CuSO4 solutions.Measure the absorbance of all four solutions that you have prepared.4.5.PROCEDURE D:On the graph provided in report sheet, plot the concentration of CuSO4 versus the absorbance ofthe solutions and answer questions.DashboardCalendarTo DoNotificationsInbox因
