How many units are in 0.5 mL of insulin if the concentration is 100 units/mL?

• A. 25 units
• B. 50 units
• C. 10 units
• D. 100 units

Answer: (B)

To determine how many units are in 0.5 mL of insulin with a concentration of 100 units/mL, the calculation involves a simple multiplication of the volume by the concentration. First, you recognize that the concentration tells us that there are 100 units of insulin in every 1 mL. To find out how many units are in 0.5 mL, you perform the following calculation: 0.5 mL × 100 units/mL = 50 units This results in a total of 50 units of insulin contained in 0.5 mL. The concentration provides a direct relationship between the volume of the solution and the total units of the active ingredient present. The result directly aligns with the answer, confirming that 50 units is indeed the correct amount derived from the specified volume and concentration.
