On a student s Beer s law calibration graph, 0.08 < A < 0.79; the equation of the best fit line was A = 0.013 C 0.025 (C has units of mg mix / L). Analysis of the student s unknown sample gave the following data: stock solution undiluted: -A offscale solution #1 10.00 mL stock diluted to 25.00 mL -A offscale solution #2 1.00 mL stock diluted to 25.00 mL -A = 0.85 solution #3 1.00 mL #1 diluted to 25.00 mL -A = 0.73 What are the concentrations of solution #3, and of the stock solution?
