Day 01 - Factor-Label Review

Your favorite! Factor-label method and dimensional analysis. Yay! Use the factor-label method to solve the following problems:

• Question 1: A piece of metal has a mass of 27.6 g and a volume of 7.72 mL. What is its density in g/cm3?
• Question 2: The density of Hg is 13.6 g/cm^3. What volume in mL does 290g of Hg occupy?
• Question 3: How many square inches are there in 85.0 cm^2?
• Question 4: The density of water is one gram per cubic centimeter. What is the density of water in pounds per liter?
• Question 4: The density of water is one gram per cubic centimeter. What is the density of water in pounds per liter?
• Question 5: The wavelength of some visible light is 706 nm. What is its frequency in sec^-1 (Hz) ? The speed of light, c = 3.00 x 10^8 m/sec.
• Question 6: A sphere has a volume of 3.75 cm^3. What is its diameter in inches? Volume of a sphere = (4/3) r^3
• Question 7: A piece of aluminum foil is 0.010 mm thick. If it weighs 0.801 g, what is its area in cm^2? The density of aluminum is 2.70 g/mL.
• Question 8: How many basketballs can be carried by 8 buses? If:
• · 1 bus = 12 cars
• · 3 cars = 1 truck
• · 1000 basketballs = 1 truck
