A researcher wants to determine the concentration of beta-carotene in carrots. She obtains a 0.609 M stock solution of beta-carotene and creates Dilution A by transferring 13.00 mL of stock solution into a new container and diluting it with solvent to a final volume of 96.00 mL. She creates Dilution B by transferring 52.00 mL of stock solution into a new container and diluting it with solvent to a final volume of 78.00 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 21.00 mL. What is the concentration in mM of Dilution C? Report your answer with one place after the decimal.
