Iam stuck on how to start this problem. Youo are presented with a sample of freshly squeezed carrot juice and are asked to determine how much beta-carotene is presented in the juice. A beer's Law plots is constructed from the absorbances at 451 nm for six standard solutions of beta-carotene, with concentrations ranging from 0.75-7.5 µM. Linear regressions data: y=0.1431x-0.0078(R2=0.9998) a)The carrot juice is diluted by one-fourth, and the absorbance at 451 nm of this solutions is measured to be 0.676. Based on this information, what is molor concentration of beta-corotene in the original(undilited) sample of carrot juice? b) If the original sample of carrot juice was 312 mL, calculated the mass(g) of beta-carotene presented
