To determine the number of units of U-100 Humulin N insulin in 0.32 mL, let's go through the detailed, step-by-step calculation:
1. Understanding U-100 Insulin Concentration:
- U-100 means that the insulin concentration is 100 units per milliliter (mL). This is a standard concentration used in insulin therapy.
2. Given Volume:
- We are given a volume of 0.32 mL.
3. Setting up the multiplication:
- To find the number of insulin units in 0.32 mL, we need to multiply the concentration by the volume.
4. Calculation:
- Number of units = Concentration (units per mL) × Volume (mL)
- Number of units = 100 units/mL × 0.32 mL
5. Result:
- Number of units = 32
So, 0.32 mL of U-100 Humulin N insulin contains 32 units of insulin.
Therefore, the correct answer is:
b. 32 units
