What is the dosage in mg of a medication given at 4 L/day at a concentration of 100 mg/100 mL?

To determine the dosage of the medication in milligrams, you need to first convert the flow rate of the medication from liters to milliliters since the concentration is provided in mg per mL.

Given that 1 liter equals 1000 milliliters, you can convert 4 liters per day to milliliters as follows:

4 L/day × 1000 mL/L = 4000 mL/day.

Next, you know that the concentration of the medication is 100 mg per 100 mL. This can be simplified to find out how many milligrams are in 1 mL:

100 mg / 100 mL = 1 mg/mL.

Now, to find the total dosage in milligrams for the 4000 mL being administered per day, you multiply the volume in milliliters by the concentration in mg per mL:

4000 mL × 1 mg/mL = 4000 mg.

Therefore, the total dosage of the medication being given at a rate of 4 L per day with a concentration of 100 mg/100 mL is indeed 4000 mg. This understanding of unit conversion and concentration calculation is essential in medical settings to ensure correct dosing.
