39. A comparison of the absorbance readings obtained in Experiment 2 with the information in Figure 1 suggests that the concentration of Mn, in mg/L, of Sample D is closest to which of the following values?
Your Answer is
Correct Answer is C
Explanation
From Table 1, find that the absorbance of sampleD is 0.5, then return to the vertical coordinate of Figure 1 to find 0.5, and find the value of the corresponding horizontal coordinate is about 1, so C is the closest
