1. Suppose that in Experiment 3 a beet section had been placed in a solution that was 40% methanol by volume for 20 min. The absorbance of the sample from the resulting solution would most likely have been closest to which of the following?
Your Answer is
Correct Answer is B
Explanation
The 40% methanol for 20 min given in the question stem is between trail 23 (30%) and trail 26 (50%) in table 3, so the absorbance is between 0.24-0.33, option B meets
