TL;DR

This video explains how percentages are used in drug calculations and demonstrates how to convert concentrations between different units of measurement.

Key Insights

• ☢️ Percentages are commonly used to represent the concentration of an active ingredient in a drug.
• 👻 Converting the concentration to mg per ml allows for easier calculations and comparison between different solutions.
• 🔇 The amount of active ingredient in a given volume of a drug solution can be determined by multiplying the concentration in mg per ml by the volume given in milliliters.

Questions & Answers

Q: What does the percentage in a drug concentration represent?

The percentage represents the concentration of the active ingredient in the drug. For example, 10% WV means there are 10 grams of the active ingredient per 100 milliliters of the drug.

Q: How can the concentration be converted from percentage to milligrams per milliliter?

To convert the concentration from percentage to mg per ml, simply multiply the percentage by 10. For example, 10% WV is equivalent to 100 mg per ml.

Q: How can the amount of active ingredient be calculated in a given quantity of a drug solution?

Multiply the concentration in mg per ml by the volume given in milliliters to calculate the amount of active ingredient. For example, if the concentration is 100 mg per ml and 20 ml of the solution is given, then 2000 mg of active ingredient is given.

Q: How can the concentration in mg per ml be converted back to percentage?

To convert the concentration from mg per ml back to percentage, divide the value by 10. For example, if the concentration is 8 mg per ml, then the percentage is 0.8% WV.

Summary & Key Takeaways

• The video explains that percentages are used to represent the concentration of an active ingredient in a drug. For example, 10% WV means 10 grams of the active ingredient per 100 milliliters of the drug.

• The video demonstrates how to convert percentages to milligrams per milliliter (mg per ml). By multiplying the percentage by 10, the concentration in mg per ml can be obtained. For example, 10% WV is equivalent to 100 mg per ml.

• The video also shows how to calculate the amount of active ingredient in a given quantity of a drug solution. By multiplying the concentration in mg per ml by the volume given, the amount of active ingredient can be determined.
