Vehicle	qs 100mL	qs 50mL


To solve this problem, we need to determine the amount of 5 mg tablets and the levigating agent required to make a mixture equivalent to 10 tablets of 10 mg, and a total volume of 50 mL.

### Breakdown:

1. **Tablets**:  
   You are given 5 mg tablets, but you need the equivalent of 10 tablets of 10 mg. So, first calculate how many 5 mg tablets will provide the equivalent of 10 tablets of 10 mg.

   \[
   \text{Required amount in mg} = 10 \times 10\, \text{mg} = 100\, \text{mg}
   \]
   Since each of your tablets contains 5 mg:
   \[
   \text{Number of 5 mg tablets} = \frac{100\, \text{mg}}{5\, \text{mg/tablet}} = 20\, \text{tablets}
   \]

   **Answer for tablets**: You will need **20 tablets** of 5 mg.

2. **Levigating Agent**:  
   The formula specifies 10 mL of levigating agent, and no scaling factor is mentioned for this component. Therefore, you will use the full 10 mL of the levigating agent.

   **Answer for levigating agent**: **10 mL**.

3. **Vehicle**:  
   The vehicle is to be used **qs 50 mL**, which means "quantity sufficient" to bring the total volume to 50 mL. The amount of levigating agent used is already 10 mL, so the remaining 40 mL will be made up by the vehicle.

   **Answer for vehicle**: **40 mL**.

### Summary:
- **Tablets**: 20 (5 mg each)
- **Levigating agent**: 10 mL
- **Vehicle**: 40 mL
