Dimensional Analysis/Accuracy&Precision/Density - Practice

502 mL = (a)   L

25.0 g = (a)   kg

25 cm = (a)   mm

If my car gets 26.0 miles to the gallon and the tank can hold 13.2 gallons of gas, how many miles can I travel?

(a)   miles

178.2 kL = (a)   cL

(For scientific notation, use the caret symbol ^ to express the exponent)

(ex: 2.00 x 10^3)

8.41 g/mL = (a)   kg/L

175 lbs = (a)   kg

(Note: 2.2 lb = 1 kg)

2.3 miles = (a)   inches

(Note: 5280 ft = 1 mile)

(Use caret ^ for exponents when reporting answer in scientific notation)

A piece of gold leaf (density = 19.3 g/cm^3) weighs 1.93 mg. What is the volume of the gold in cubic millimeters (mm^3)?

(a)   mm^3

Which is a better deal:

1) One gallon of gasoline for $2.89

2) One liter of gasoline for $0.75?

(Note: 1 gallon = 3.785 liters)

• Option 1

• Option 2
