Consider the Data Table below:

a) Determine the equationof the line that bestfits the data.

b) Suppose you have a sample that gives an instrument response of 5.67.  This value is higher than the reading of the highest standard in the Table below. Therefore, you dilute the sample 1:5. The instrument reading of the dilutedsample is 1.81.  What was the concentration of the material of interest in the original solution?  Show work.

Below is the background info for the lab assignment. The 4 blank boxes are the questions I would like answers too. The end point for the fine titration was 35.90 mL in the burette when the solution turned bright green again. And the coarse titration I got 35.36mL as the end point. 35.9 mL is exact in case you need that info. Thanks!
