The case study will include a Synopsis and three Findings of Fact. Each Finding of Fact will require a justified recommended solution. Students should support their recommended solutions with rational thought learned from the course material, other courses, www resources provided for this course, and real-life experiences.
Photometric measurement for the phosphate in a 25mL aliquot showed an absorbance of 0.428. Addition of 1mL of a solution containing 0.500mg phosphate to a second 25 mL aliquot yielded an absorbance of 0.517. Calculate the mg of phosphate in each m..
