Previously Sci-ber text gave you the opportunity to calculate density. Remember the formula is: . Data has been collected for things found naturally on the Earth. There is nothing "tricky" about this data. In fact, if you wish, you may use a calculator to assist you!

Now you need to test your math ability! Use the data in the table below to calculate the densities of some common materials on earth.

Mass in grams
Volume in cubic centimeters
Density in grams/cubic centimeters
1. Gold 193.2g 10 cm3  
2.Oxygen 1.33g 100 cm3  
3.Water 10.0g 10 cm3  
4.Helium 1.663g 10,000 cm3  
5.Mercury 67.75g 5 cm3  
6.Copper 224g 25 cm3  








After completing your calculations check your answers by highlighting the box below.

1. 19.32 g/cm3, 2. .001331 g/cm3 , 3. 1 g/cm3, 4. 0.0001663 g/cm3, 5. 13.55 g/cm3, 6. 8.96 g/cm3
