If 250 mg of penicillin VK is equivalent to 400,000 Units, how many Units are in 1 mg of penicillin VK?

To determine how many Units are in 1 mg of penicillin VK, you can begin by understanding the relationship given: 250 mg of penicillin VK corresponds to 400,000 Units.

To find the number of Units in 1 mg, you can set up a conversion factor. Start with the information that 250 mg equals 400,000 Units. The first step is to find out how many Units are in 1 mg by dividing the total Units by the total mg:

400,000 Units / 250 mg = 1,600 Units per mg.

This calculation indicates that for each milligram of penicillin VK, there are 1,600 Units. Therefore, the correct response reflects this calculation, indicating that 1 mg of penicillin VK is equivalent to 1,600 Units.
