Answer:
The correct answer is that James need 8/27 of hydrogen peroxide to prepare the bulk compound
Step-by-step explanation:
Amount of hydrogen peroxide retrieved by James = 2/3
Amount of hydrogen peroxide instructed by the pharmacist = 4/9 of the amount of hydrogen peroxide retrieved by James
Amount of hydrogen peroxide instructed by the pharmacist = 4/9 of 2/3
Amount of hydrogen peroxide instructed by the pharmacist = 4/9 * 2/3
Amount of hydrogen peroxide instructed by the pharmacist = 8/27
According to the pharmacist instructions, James need 8/27 of hydrogen peroxide to prepare the bulk compound
