To what volume should you dilute 125 mL of an 8.15 M CuCl2 solution so that 52.0 mL of the diluted solution contains 4.78 g CuCl2? Express your answer in milliliters.
Firefly luciferase is the enzyme that allows fireflies to illuminate their abdomens. Because this light generation is an ATP-requiring reaction, firefly luciferase can be used to test for the presence of ATP.
