A researcher wants to determine the concentration of beta-carotene in carrots. She obtains a 0.558 M stock solution of beta-carotene and creates Dilution A by transferring 15.00 mL of stock solution into a new container and diluting it with solvent to a final volume of 90.00 mL. She creates Dilution B by transferring 53.00 mL of stock solution into a new container and diluting it with solvent to a final volume of 80.00 mL. She creates Dilution C by transferring 2.00 mL of Dilution B into a new container and diluting it with solvent to a final volume of 15.00 mL. What is the concentration in mM of Dilution C? Report your answer with one place after the decimal. Remember to draw a dilution scheme!
