Final answer:
To administer 1 gram of the medication, 2 mL will be administered.
Step-by-step explanation:
To determine how many mL of the medication will be administered, we need to convert the grams into mL using the given concentration. The concentration is 0.5 grams per mL, and the physician wants to administer 1 gram of the medication. To find the volume in mL, we can divide the 1 gram by the concentration of 0.5 grams per mL:
1 gram ÷ 0.5 grams per mL = 2 mL
Therefore, 2 mL of the medication will be administered.
