For calibration of an instrument to measure the Zinc concentration in a given volume of contaminated water, a serial dilution of a stock solution of Zinc were made using MIVI = M2V2. Calibration Graph and correlation Coefficient R2
Volume in mL:    1000                 250                       125       50          25          0
[Zinc] PPM            500                   125                       62.5       25         12          0
What does R2 and R tell us?2.You were given contaminated water from St Bernard LA and you did a double two fold dilutions and analyze 100 ml of it. Using the calibration curve above, estimate the Zinc concentration in the diluted and concentrated St. Bernard water samples?
