Section 1: Complete problems 34, 38-43, 45 - 48 and 58 on pages 60-61 of your textbook in your notebook. Remember that the answer to all calculation problems should have the correct number of sig figs!
1. A block of aluminum occupies a volume of 15.0 mL and weighs 40.5 g. What is its density?
2. Mercury metal is poured into a graduated cylinder that holds exactly 22.5 mL. The mercury used to fill the cylinder weighs 306.0 g. From this information, calculate the density of mercury.
3. What is the weight of the ethanol that exactly fills a 200.0 mL container?
The density of ethanol is 0.789 g/mL.
4. What volume of silver metal will weigh exactly 2500.0 g. The density of silver is 10.5 g/cm3.

You can tell someone how tall you are, how heavy you are, how much space you take up. Even though all of these things are descriptive of you, they would all be measured in very different ways.

Sections 1&2: Take two of the items you measured last night and "measure" them again, but this time you are not allowed to use any formal measurement system - you must create your own!! If you cannot bring in your created measurement tool, make sure to take a picture on your phone while you're measuring! Think outside the box!!
Section 3 & 7: Please bring in the item you measured last night, or another item that can be easily measured. Bringing in your measured item from last night's homework is ideal!
Also, watch this video:
