## Data Analysis

Review Game

• 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 milligrams are in 0.040 grams?

• .040 g (1000 mg/1 g) = 40 mg

• How many centimeters are in 267 millimeters?

• 267 mm (1 cm/10 mm)= 26.7 cm

### 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

### 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

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.
