### CHEMISTRY 3A --- WORKSHEET 1#### CHAPTERS 1 AND 81. **Distance Conversion Problem** - **Problem Statement**: A runner runs for a distance of 350 yards and then runs for an additional 200 meters. What is the total distance covered by the runner in meters?2. **Volume Conversion Factor** - **Problem Statement**: A can of Schweppes Ginger Ale contains a volume of 12 fluid ounces or 355 mL. Using this information, determine the conversion factor between mL and fluid ounces. Be sure to reduce the conversion factor.3. **Calorie Calculation** - **Problem Statement**: The "Farmhand Cut" of prime rib at Farmer Browns Steak House weighs in at 20 ounces, of which 6.0 ounces is good old Nebraska beef fat. A person on a 2400 calorie per day diet should not consume more than 800 calories from fat. If fat contains 9.0 calories per gram, is this steak within the 800 calorie limit? **Problem 4: Assessing the Purity of the King's Crown**In a land far away, long, long ago, the king sent to the royal goldsmith a five-pound ingot of pure gold. "From this gold," commanded the king, "fashion for me a crown." When the crown was presented to the king, he wondered whether the crown was truly pure gold or if the greedy goldsmith had cheated him by replacing part of the gold with copper. The king asked the court chemist to determine, without damaging the crown, whether it did indeed consist of pure gold. The chemist, being a clever soul (aren't they all), weighed the crown and found that it did, in fact, weigh precisely five pounds. The chemist then proceeded to immerse the crown in a flask of water. The flask, which initially contained 1000 mL of water, now appeared to contain 1170 mL of water. Knowing that the density of pure gold is 19.3 g/mL, what did the chemist tell the king?**Problem 5: Medication Dosage Calculation**Every six hours, a patient requires a 50 mg dose of a drug for each kilogram of body weight. If the patient weighs 115 lb, how much of the drug will be required for each dose? If the drug is administered as an I.V. solution containing 13 mg of drug per mL of solution, how many mL will be required each day?

Leaming Goal: meanings and see that mili means 103. Therefore, To convert between metric units expressing length, area, and volume. 1 m %3D 1000 mm The ability to convert from one system of units to another is important in chemistry. It is often impractical to measure quantities in the standard meters, kilograms, and seconds, but the laws of science that you learn will involve constants that are defined in these units. Therefore, you may often have to convert your measured quantities into different metric units. The following table lists metric prefixes that come up frequently in chemistry. Learning these prefixes will help you in the various exercises. Once you know this, you need to divide one side by the other to obtain a ratio of m to mm: 1 m 1 1000 mm If you are converting from millimeters to meters, then this is the proper ratio. It has mm in the denominator, so that it will cancel the units of the quantity that you are converting. For instance, if you were converting 63 mm, then…
The density of a metal is 8.67 g/cm3. How many pounds are in 298.86 in of the metal? (You can use the conversion factor approach. Or, you can convert density in g/cm to Ib/in and then multiply the result times number of pounds. 2.52 cm = 1 inch 454 g = 1 lb Please see 'answers to extra problems' question 10 for hints on how to do this.) You need to write your answer in the box with one number past the decimal. Please don't worry about the sig figs in this case. In these formula problems, the Canvas software will give a variety of questions and each student gets their data with different sig figs. So I just have to choose and sometimes it might seem that one past the decimal is not the correct sig figs. Nonetheless, you have to follow that direction.
