 Do all work on a separate sheet of paper. The conversions you are about to do is a process in chemistry called _____________ _____________. Convert each of the following measurements to its equivalent in the units given. Show every step, do not take short cuts. Do not just move the decimal point. SHOW ALL WORK! 1) 73 centimeters to meters 21) 11.0 oz to cg 2) 51 pounds to ounces 22) 3.4 qt to mL 3) 235.7 liters to kiloliters 23) 0.051 km to mi 4) 8.72 grams to milligrams 24) 6.4 gal to qt 5) 0.023 miles to feet 25) 0.895 kg to tons 6) 19 gallons to cubic feet 26) 157 yd to km 7) 67.8 centigrams to ounces 27) 89.9 lb to g 8) 5.783 liters to quarts 28) 50000 mm to mi 9) 23.6 feet to centimeters 29) 86000 sec to days 10) 892 hours to years 30) 586 cm3 to gal 11) 88 grams to pounds 31) 13 mi to km 12) 19.1 yards to centimeters 32) 0.0793 kg to mg 13) 413.3 yards to miles 33) 55.7 qt to L 14) 1.00 inches to meters 34) 40.71 years to min 15) 14.587 milligrams to grams 35) 453.7 yd to in 16) 0.895 kiloliters to liters 36) 433 cm3 to kL 17) 0.050 pounds to kilograms 37) 4053 oz to kg 18) 148 cubic centimeters to cubic feet 38) 352.6 m to ft 19) 17 quarts to cubic feet 39) 461.57 sec to hr 20) 1406.78 centimeters to yards 40) 4.75 tons to kg The metric system has three base units. For length it is ___________, for mass it is _________ and for volume it is ____________. _____________ is neither a Metric nor an English unit, but a universal unit. By using different combinations of these four units we can determine three new measurements. The first is density. Density is the ratio of the ____________ of an object to the _____________ of the object. The second new measurement is speed. Speed is the ratio of _____________ an object travels to the _____________ it takes an object to travel that far. The final measurement is flow rate. Flow rate is the ratio of the ___________of a fluid to ___________. DENSITY = mass (g) SPEED = length (m) FLOW RATE = volume (mL) volume (mL) time (s) time (s) 41) 20.6 kilometers per hour to meters per second Convert to Scientific Notation 42) 7.3 milliliters per second to cubic feet per day 59) 3,987 43) 97 grams per milliliter to pounds per gallon 60) 0.00563 44) 14.7 pounds per cubic foot to kilograms per liter 61) 602,000,000,000,000,000,000,000 45) 19.8 miles per hour to feet per minute 62) 0.00000000000000091 46) 90 gallons per hour to cubic centimeters per second Convert to Decimal Form 47) 98 mi/hr to m/s 63) 9.87 x 10-2 48) 176.89 qt/min to gal/sec 64) 4.321 x 1013 49) 0.167 kg/L to g/mL 65) 3.684 x 10-17 50) 9.23 x 107 cm/hr to yd/week 66) 7.56432 x 103 51) 3.568 x 10-5 kL/hr to qt/day Convert to Proper Scientific Notation 52) 3 x 103 oz/qt to cg/L 67) 345.76 x 10-65 53) 8.4 x 10-6 kilograms to centigrams 68) 0.009513 x 102 54) 2.36 x 104 seconds to days Solve, answer in Scientific Notation 55) 9.96 x 10-11 miles to millimeters 69) (9.73 x 107) (5.31 x 10-36) 56) 1.537 x 102 quarts to gallons 70) (1.5531 x 108) (8.85 x 102) 57) 3.7 x 10-4 milliliter per second to cubic feet per day 71) (7.538 x 106) / (8.96 x 10-5) 58) 8.05 x 105 grams per milliliter to kilograms per liter 72) (9.213 x 10-14) / (4.36 x 105)
