Answer:
Explanation:
From the given information:
The mean of the readings is:


= 157.1
The standard deviation (SD) can be computed by using the expression:


Standard deviation = 28.195
∴
FOr the EDTA complexes;
The signal detection limit = (3*SD) +

= (3*28.195) + 50
= 84.585 + 50
= 134.585
We need to point out that the value of the calibration curve given is too vague and it should be (1.75 x 10^9 M^-1) as oppose to (1.75 x 10^-9 M^-1)
The concentration of detection limit is:



The lower limit of quantification is:
