Calculate the dosage of medication in mL if a doctor prescribes 750 mg of a medication that has a concentration of 150 mg/mL.

To determine the correct dosage of medication in mL, we can use the formula that relates the dose in mg to the concentration in mg/mL. This formula can be expressed as:

Dosage (mL) = Amount prescribed (mg) / Concentration (mg/mL)

In this scenario, the doctor prescribes 750 mg of the medication, and the concentration is given as 150 mg/mL. Plugging in the values:

Dosage (mL) = 750 mg / 150 mg/mL

When we calculate that, we perform the division:

Dosage (mL) = 750 / 150 = 5 mL

Thus, the correct dosage for the medication is 5 mL. This calculation shows how the prescribed amount is directly related to the concentration of the medication, resulting in the volume needed for proper administration.
