You will likely need to adjust the sig fig display for the R₂ value andlinear trend-line equation in EXCEL. Properly title the plot and label the axescorrectly. Use reasonable sig figs and correct units. Paste in the complete plot below. Instructions. Carefully review the Constant-Volume Standard Addition material (pages 7 - 13) of the CHEM146 Lab 2 Manual given its central importance (especially the fully worked example on pages 11 - 13). In thisonline activity, you are processing and analyzing raw FAAS data identical to what you would obtain in lab.FAAS Lead Analysis by Constant-Volume Standard Addition. Assume we wish to find the Lead (Pb)concentration in ppb for a lake water sample (the "unknown"). Using a pipette, 10.00 mL of lake water isloaded into five 50 mL volumetric flasks. Next, exactly 0.00, 5.00, 10.00, 15.00 and 20.00 mL of standard leadsolution at 4.96 ppb (parts per billion) is added. After dilution to the volume, FAAS readings at λ = 283 nm aretaken of the five solutions. The resulting absorbance values are presented below.Table 2-1.
