What is the total volume of 200mg of medication if the concentration is 50mg/ml?

To determine the total volume of 200 mg of medication with a concentration of 50 mg/ml, you can use the formula for calculating volume based on the amount of substance and its concentration. The formula is:

Volume (ml) = Amount (mg) / Concentration (mg/ml)

Substituting the values into the formula gives:

Volume (ml) = 200 mg / 50 mg/ml

When you perform the division:

200 mg ÷ 50 mg/ml = 4 ml

This calculation shows that the correct total volume required to achieve a dose of 200 mg, when the concentration is 50 mg/ml, is indeed 4 ml. This means that if you have a solution where each milliliter contains 50 mg of medication, you would need 4 ml of that solution to obtain a total of 200 mg of the medication. Therefore, the total volume of medication in this concentration is accurately determined to be 4 ml.
