Data Analysis Review Game Put the following numbers into scientific notation • • • • • • 6,401 6.401 x 103 80,000,000 8 x 107 .0099 9.9 x 10-3 Convert the following: • • • • • • 1 kL is equal to _______ liter(s). 1000 How many milliliters are in 0.040 liters? .040 L (1000 mL/1 L) = 40 mL How many centimeters are in 267 millimeters? 267 mm (1 cm/10 mm)= 26.7 cm Round each number to four significant figures. • • • • • • 431 801 kg =431 800 kg 10 235.0 mg =10 240 mg 1.0348 m =1.035 m Using the rules of sig figs, calculate • • • • • • 826.09 + 1.097 + 3.4 + 200 = 1030.587 = 1031 826.077 + 1.017 + 3.4 + 200 = 1030.494 = 1030 826.083 + 1.117 + 3.3 + 200= 1030.5 = 1030 Using the rules of sig figs, calculate • • • • • • • • 4.87 x 104/8.90 x 10-9 = 5.47 x 1012 2 x 1013 x (6000 x 107) = 1.2 x 1024 = 1 x 1024 69 x .50 = = 34 60.0 x 4 = = 200 Complete the following addition and subtraction problems in scientific notation. • • • • (6.23 x 106 kL) + (5.34 x 106 kL) = 1.16 x 107 kL (5.72 x 10-4) dg) – (2.3 x 10-5 dg) 5.5 x 10-4 dg Convert 80.5 lbs to kilograms (1 lb = 453.6 g) • 80.5 lbs (453.6 g/1 lb)(1 kg/1000 g) = • 36.5148 = 36.5 kg An empty graduated cylinder weighs 53.02 g. When filled with 25.0 mL of an unknown liquid, it weighs 76.12 g. The density of this liquid is • D = g/mL; 76.12-53.02 = 23.10 g • 23.10 g/25.0 mL = .924 g/mL The density of aluminum is 2.7 g/mL. What is the volume of 8.1 g? • 3.0 mL You are in Paris and wish to buy some peaches for lunch. The sign in the fruit stand indicates that peaches are 20.5 francs per kilogram. Given that there are approximately 5 francs to the dollar, and that one pound equals approximately 453.6 grams, calculate what a pound of peaches would cost in dollars. 1 lb • =$1.86 453.6 g 1 kg 20.5 francs 1 dollar 1 lb 1000 g 1 kg 5 francs
