Metal Density g/cm3

Aluminum 2.7

Brass 8.5

Copper 8.9

Gold 19.3

The table provided identifies a substance based on its density.

A sample of an unknown substance has a mass of 27 grams and a volume of 10 cm3. What is the unknown substance based on its density?

10/21/14 No warm up today. Get your Journal and start a table of

contents page “Mineral Man Pre-writing”

1. Choose your mineral2. Research your mineral in your workbook

or online. Remember anything you use in your final copy you must site your resources at the end of your paragraph.

3. Begin brainstorming superhero powers and costume. Write ideas in your journal.

4. Start rough draft of picture or paragraph.

Mohs Hardness Scale

1 – Talc

2 – Gypsum

3 – Calcite

4 – Fluorite

5 – Apatite

6 – Orthoclase Feldspar

7 – Quartz

8 – Topaz

9 – Corundum

10 – Diamond

1. List the following minerals from most hard to least hard.

Talc, Corundum, Quartz, Calcite

2. A certain mineral sample cannot scratch Fluorite, but Fluorite can scratch the sample. What are the possible values of the mineral’s hardness?

10/23/14 WARM UPBased on the data for the four samples, determine which of the following substances has the greatest density.  A. Sample 1: volume = 15cm3, mass = 30 gB. Sample 2: volume = 20cm3, mass = 66 gC. Sample 3: volume = 3cm3, mass = 12 gD. Sample 4: volume = 48cm3, mass =100 g
