Density Review

A metal cube was measured to have a mass of 350 grams. By water displacement, the volume of the beads was calculated to be 60 mL. Given the following densities, what is the substance? (Remember: Density = Mass/Volume)

• Lead - 4.26 g/mL

• Bronze - 5.83 g/mL

• Copper - 6.75 g/mL

• Silver - 4.37 g/mL

The mass of an unknown substance is 200 grams. Its volume is 12 cm3.

Substances' Density:

W - 20 g/cm3

X - 16.66 g/cm3

Y - 18 g/cm3

Z - 12.25 g/cm3

According to the information above, which substance is being described?

• W

• X

• Y

• Z

A sample of Titanium is shown. Calculate the density of the sample and fill in the blank.

The density of Sample A is ________ g/cm3.

How does the density of an object relate to its mass?

Does the density of a substance change depending on the amount of it you have?

 $Density\ =\ Mass\ \div\ Volume$  

Use the two graphs.

Step 1: Calculate the densities of the Unknown Substances 

Step 2: Using the Table of Density of Known Substances to identify the substance below.

I think substance 1 is _______.
