CHEMISTRY 2001 NAME PROBLEM SET #2: CONVERSION BETWEEN UNITS DATE PERIOD I. BACKGROUND: Listed below are some conversion factors that may be helpful in solving the problems in this set. Since each of these conversion factors is actually a DEFINITION, NOT A MEASUREMENT, each is precise to infinitely many significant figures. For example, there is EXACTLY 1 inch in EXACTLY 2.54 centimeters. This means that an object that is 2.5400 cm in length is 1.0000 in in length, even though the conversion factor only “seems to” have one sig- fig! LENGTH VOLUME MASS 1 in = 2.54 cm 1 c = 8 fl oz 1 kg = 2.2 lb 1 km = 0.6 mi 1 pt = 2 c 1 lb = 16 oz 1 mi = 5280 ft 4 c = 1 qt 4 qt = 1 gal 1 L = 1.1 qt II. SAMPLE PROBLEM: 1.00 qt = ? L 1.00 L | 1.00 qt | x | ------------- | = 0.909 L = 9.09 x 10 -1 L 1.10 qt III. PROBLEMS: Convert each measurement into the new unit by using the Unit Factor Method. For some conversions,

Unformatted text preview: you may need to make multiple conversions. SHOW ALL YOUR WORK!!!!! CIRCLE YOUR FINAL ANSWER WITH ITS UNIT . ALL ANSWERS SHOULD BE IN SCIENTIFIC NOTATION WITH THE CORRECT NUMBER OF SIG-FIGS . 1. 1.00 ft = ? cm 2. 1.000 yd = ? cm 3. 1.00000 m = ? in 4. 1.00 mi = ? yd 5. 1.000 kg = ? oz 6. 1.00 gal = ? fl oz 7. 2.90 ft = ? mm 8. 127.30 km = ? in 9. How many seconds are in 1.00 week? 10. How many minutes are in 0.500 year? How the Pros Do It: Multiply your original measurement by a constant. The constant should have the UNIT YOU WANT ON TOP, and the UNIT YOU WISH TO CANCEL ON THE BOTTOM. Fill in the correct numerical values so the constant represents unity (1), and then perform your calculation!...
