Answer: So, 100 milliliters should be given to the patient.
Step-by-step explanation:
To find out how many milliliters should be given to the patient, we can use the formula for concentration:
Concentration = Amount of Medication / Volume
Given that the concentration is 20 mg/mL and the doctor orders 2 g of medication, we first need to convert the amount of medication from grams to milligrams:
2 g = 2000 mg
Now, we can rearrange the formula to solve for volume:
Volume = Amount of Medication / Concentration
Substituting the given values:
Volume = 2000 mg / 20 mg/mL
Volume = 100 mL
