Often the specific amount of a drug to be administered must be calculated from a given dose in mg per kilogram of body weight. This assures that individuals who have very different body mass get the proper dose. If the proper dosage of a drug is 2.0 mg/kg of body weight, how many milligrams would a 165 lb person need?

**Text Transcription for Educational Purposes:** 1. After you have worked out at the gym on a stationary bike for 45 minutes, the distance gauge indicates that you have traveled 15.2 miles. What was your rate in km/hr? 2. If a urine sample has a mass of 122 g and a volume of 121 mL, what is its density in g/mL? **Explanation:** These questions are designed to practice conversion and calculation skills related to distance, speed, and density. The first question focuses on converting the biking speed from miles per 45 minutes to kilometers per hour. The second question involves calculating the density of a substance by using its mass and volume. Both exercises are typical in educational settings where mathematical modeling and unit conversion are taught.
