13. The density of aluminum is 2.70 g/mL. If the mass of a piece of aluminum is 0.244 kilograms, what is the volume of the aluminum?

14. A little aluminum boat (mass of 14.50 g) has a volume of 450.00 cm3. The boat is place in a small pool of water and carefully filled with pennies. If each penny has a mass of 2.50 g, how many pennies can be added to the boat before it sinks?

15. A sample of oxygen (O2) gas has a mass of 32650 milligrams and a volume of 24.924 L. What is the density of the O2 gas?

21. If you measured the density for a block of wood and then cut the wood in half and measured the density of one of the halves, would you get different values for density? Why or why not?

24. If a block of copper measures 2.00 cm x 4.00 cm x 5.00 cm and weighs 356 grams, what is its density?

28. A student pipettes 5.00 mL of ethanol into a flask weighing 15.25 grams. She finds that the mass of the flask plus ethanol = 19.17 grams. Calculate the density of ethyl alcohol.

29. Peanut oil has a density of 0.92 g/mL. If a recipe calls for ¼ cup of peanut oil, what mass of peanut oil is required? (Hint: 1 cup = 237 mL).

30. A sample of lead is found to have a mass of 32.6g. A graduated cylinder contains 2.8 mL of water. After the lead sample is added to the cylinder the water level reads 5.7mL. Calculate the density of the lead sample.
