Final answer:
In the compounding process, the two items that need to be compared to verify accuracy are the target value and the actual volume dispensed by the machines.
Step-by-step explanation:
In the compounding process, there are two items that need to be compared to verify accuracy. The first item is the target value, which is the desired amount of the substance you are compounding. In this case, it is 10 ounces (296 mL) of cough syrup. The second item is the actual volume dispensed by the machines. By comparing the actual volume with the target value, you can determine if the machines are accurate in dispensing the desired amount of cough syrup.
