8 Conversions Reg Chemistry 1. In the United Kingdom, British Rail runs two types of modern high speed passenger trains. The Intercity-125 and the Intercity-225. The Intercity-125 has a top speed of 125 mi/hr, whereas the newer Intercity-225 has a top speed of 225 km/hr. Which train is faster? 2. The radius of an atom is 1 x m. What is this radius in centimeters? In inches? 3. You are in Paris, and you want to buy some peaches for lunch. The sign in the fruit stand indicates that peaches are 11.5 francs per kilograms. Given that there are approximately 5 francs to the dollar, calculate what a pound of peaches will cost in dollars. 4. At the mall, you decide to try on a pair of Italian jeans. Naturally, the waist size of the jeans is given in centimeters. What does a waist measurement of 52 cm correspond to in inches?

9 5. You pass a road sign saying New York, 110 km. If you drive at a constant speed of 65 mi/hr, how long should it take you to reach New York? 6. For a pharmacist dispensing pills or capsules, it is often easier to weigh the medication to be dispensed rather than to count the individual pills. If a single antibiotic capsule weighs 0.65 g, and a pharmacist weighs out 15.6 grams of capsules, how many capsules have been dispensed? 7. Earth is approximately 1.5 x 10 8 km from the sun. How many minutes does it take light to travel from the sun to Earth? The speed of light is 3.0 x 10 8 m/s? 8. What is the price of a piece of gold wire 445 centimeters long that sells for \$12.25 per foot?

10 9. The recommended adult dose of dextromethorphan, a drug used to treat cold is 35 mg/kg of body mass. Calculate the dose in milligrams for a 175 lb person. 10. A rectangular box is 4.00 in. wide, in. long, and 16.0 in. deep. Calculate the volume in both cubic centimeter and in liter. 11. A car travels 35 miles on one gallon of gasoline. How many kilometers on one liter will it go? 12. A common brand of cough syrup comes in a 4 fl oz bottle. The active ingredient in the cough syrup is dextromethorphan. For an adult, the standard dose is 2 teaspoons, and a single dose contains 20.0 mg of dextromethorphhan. Using the relationships, 1 fl oz = 29.6 ml and 1 teaspoon = 5.0 ml, determine how many grams of dextromethorphan are contained in the bottle

12 Metric to Metric Conversions The essence of metric to metric conversions is recognizing the abbreviated base units. Base Units: m (meter), L (liter), g (gram), s (seconds) These are not all of the base units, but are the most common that you will encounter. Each base unit can have any of the prefixes listed in the chart below. As with any other prefix, the prefix means the same thing regardless of the abbreviated base unit it is attached to. Giga (G) it takes 10 9 (billion) base units = 1 G Mega (M) it takes 10 6 (million) base units = 1 M Kilo (K) it takes 1000 base units = 1 K Hecto (H) it takes 100 base units = 1 H Decka (Da) it takes 10 base units = 1 Da Base Units: m, L, g, s Deci (d) it takes 1 base unit = 10 deci Centi (c) it takes 1 base unit = 100 centi Milli (m) it takes 1 base unit = 1000 milli Micro ( ) it takes 1 base unit = 10 6 (million) micro Nano (n) it takes 1 base unit = 10 9 (billion) nano There are two ways to work metric to metric conversions. The first way is to do the math by using the numerical conversion relationships listed in the chart above. Ex: Convert 35 g to g.? g = 35 g x 1 g = g 1,000,000 g The other way is to count the lines in the chart (every line except the one you start on), start from your given information and counting each line until you get to what you want to convert. ***Move Up the chart: Move decimal to the LEFT ***Move DOWN the chart: Move decimal to the RIGHT (remember RIGHT DOWN to the nitty gritty) Ex: Convert 35 g to g. Begin at prefix (micro) and count UP to g (gram). You counted UP six places, therefore you move your decimal to the LEFT six places. If your decimal is not shown, it is understood to be at the end of the number. 35. g = g Ex: Convert 0.26 ML to ml Begin at prefix M (mega) and count DOWN to prefix m (milli). You counted DOWN nine places, therefore, you move your decimal to the RIGHT nine places. So, you will add seven zeros ML = 260,000,000. ml PRACTICE PROBLEMS (and solutions) ON BACK

13 PRACTICE PROBLEMS 1) m = cm 2) 564 Dag = g 3) 58 dg = mg 4) 600 L = KL 5) Km = mm 6) 49 Hg = g 7) 210 cl = dl 8) 4.51 x 10 3 L = ml 9) cg = Kg 10) 24.6 KL = L 11) 82.4 nm = m ANSWERS 1) cm 2) 5640 g 3) 5800 mg 4) KL 5) mm 6) 4900 g 7) 21.0 dl 8) 4.51 ml; write out 4.51 x 10 3 L = 4510 L, the decimal is understood to be after the zero. Now count UP from the prefix to the m (milli) prefix. You counted three places, so move the decimal to the LEFT three places = 4.51 ml 9) Kg 10) 2.46 x L or 24,600,000,000 L 11) m
