What is the analyte's concentration, CA, and its uncertainty if Stotal is 24.370.02, S is 0.960.02, and kA is 0.1860.003ppm1, when the relationship is: Stotal=kACA+S Report the answer as XYZ ppm +/- A ppm (Example: 124 ppm +/- 6 ppm - Note A Question 2 (2 points) The concentration of C29H60 in summer rainwater collected in Hannover, Germany, is 34ppb. Find the molarity of C29H60 and express the answer in nM (nano molarity), 2 S.F, no scientific notation and no units. A Question 3 (2 points) Ba(ClO4)2 solution? 100. ml 150. ml 50.0ml 200.00ml None of those 125ml
