This is your experimental data for Experiment #3, Determinationof Copper in an Ore Sample.Your sample weighed 0.1320 gramsAfter you dissolved your sample and diluted to 50 mL in avolumetric flask, you used a 3.00 mL volumetric pipetteto remove sample solution and dilutedto 250.00 mLs.You made your standards, and when you measured them on the AtomicAbsorption Spectrometer produced the following data:The blank had an absorbance of 0.0029A 2 mg/L standard has an absorbance of 0.1337A 4 mg/L has an absorbance of 0.2670A 6 mg/L has an absorbance of 0.4038A 8 mg/L has an absorbance of 0.5336The unknown had an absorbance of 0.1955The tap water had an absorbance of 0.0048Produce and submit a spreadsheet with a PROPERLY LABELLEDcalibration curve graph with a linear least square calculation ofthe best fit line.Calculate the following in CLEARLY LABELLED cells in yourspreadsheetThe slope = The intercept = The R2 value = The copper wt% in the solid unknown you were given= %The concentration of copper in your tap water = mg/L
