Question
**Title: Calculation of Medical Components from Polymer Starting Material**

**Introduction:**
In this module, we will explore how many units of syringe connections can be produced from one metric ton of PEI plastic, equivalent to approximately 2205 pounds.

**Starting Material:**
- **PEI (Polyetherimide) Plastic**
- The starting material is depicted in a photograph showing assorted polymer granules in various colors.

**Conversion Factor:**
- **1 metric ton = 2205 lbs**

**Calculation for Number of Units of Each Component:**
- **Formula:**
  \[
  \text{Total units of medical component} = \frac{\text{Total weight of starting material PEI}}{\text{Unit weight of medical component}}
  \]

This equation assumes the entire starting material is consumed in making the components.

**Products:**

1. **Stopcock with Luer Connection:**
   - Type: 1-way male lock
   - **Unit weight:** 2.72 g = \(\frac{3}{500}\) lbs

2. **Female Luer Lock:**
   - Size: 3/16"
   - **Unit weight:** 0.63 g = \(\frac{7}{5000}\) lbs

**Instructions:**
- Perform the calculations to find out the number of units for each medical component.
- If necessary, round the results to the nearest whole number.

**Diagram Explanation:**
The diagram includes visual representations of the medical components:
- **Stopcock with Luer Connection** is shown in blue with a locking mechanism.
- **Female Luer Lock** is depicted as a transparent connector.

**Conclusion:**
Utilize the provided formula to determine the number of units each component can yield before advancing further in the module.
